In what way? No copy was ever made.

Using a copyrighted work without license is copyright infringement. Not sure how to make that clearer to you.

> Using a copyrighted work without license is copyright infringement

Only for the kinds of “use” that involve the exclusive rights of the copyright owner (“use” generally does not), and even then not always, because there are exceptions to copyright.

> This kind of thing _should_ 100% be legal (if it isn't already, and my understanding is that it is). It may fall afoul of the (terribly written, but still law) Section 1201 of the DMCA, if it's arguable that the circumvention provides access to computer software (and I think it is arguable). I agree that this should be legal , but I'm not nearly as convinced that it is legal currently.

Agree with this. The DMCA makes stuff like this illegal. Recall that when CD copy protection was starting to be deployed, you could negate it with a black marker. The DMCA then made black markers illegal, because it bans "tools which may be used to circumvent copyright" as well as the "circumvention of copy protection measures". (Not that anyone tried to enforce it, but the letter of the law was pretty clear that bla…

But they don't own the license to use the software (Full Self Driving). I agree with you about the heated seats though.

The article claims this is not patchable but it also says that the hackers have not yet unlocked FSD with this technique. I strongly suspect that the “unpatchable” part would not apply to any potential FSD unlock because of the large amount of server-side functionality involved for FSD. Server side components aren’t going to be easily fooled by a car-local exploit. Knowing Tesla, even if they can’t patch the vulnerab…

I'm torn. On one hand, I absolutely think that a capability available in the vehicle/device when you purchased it should be available for you to use, and not behind a software lock (heated seats, etc). On the other hand, an "upgrade" or 100% new software delivered via OTA (self driving, etc) seems a little more like it should be a separate thing.

> I absolutely think that a capability available in the vehicle/device when you purchased it should be available for you to use, and not behind a software lock (heated seats, etc). While I intuitively agree with you, I'm having a hard time arguing against the economic argument in favor it. Producing a single version of a product is generally cheaper than producing two different versions. Also offering a lower-margin,…

Producing the extra weight of the seat heater requires extra fuel to burn. Now multiply that by the number of cars on the road. Will cost the customer a (small) amount extra in fuel costs for a part that is not being used. So there is an economic argument that ya, we can subsidize manufactures by taxing people more. Seems like a bad deal to me.

Now lets talk about CO2 output of driving around extra dead weight. Makes it worse.

I enthusiastically endorse this sentiment until I remember I'm a software engineer whose career depends pretty fundamentally on copyright law. As an industry, we sell things that make hardware more useful. That's what software is. But the software we sell* comes with legal restrictions on what the buyer* can and can't do with it. Which means that we're restricting what our customers can do with the hardware that they…

This is probably not productive, but I think the response would be; I bought the software from you so it's mine now.

Yeah these discussions always give me a bit of cognitive dissonance.

On one hand, I like owning my software or content I purchased (talking about DRM)

On the other, people expect most things to be a "live service" in terms of updates, which isn't sustainable if you only ever get paid a small onetime fee for your software. If you make the fee large, like Modo/Photoshop did, then it acts as a financial gatekeeper to your product. Even then, I feel like it creates wrong incentives for the product, so I'm not sure it's good either.

I'm somewhat torn too. IBM and I'm sure others have shipped enterprise hardware for years that was partially locked. You might get a machine with 16 cpus but you only paid for 8, for example, but you could license the rest as you grew. It seems a little similar and it was in no way underhanded, everyone knew what the deal was. However I'll echo what another poster said. I say Tesla should be free to sell whatever the…

> I say Tesla should be free to sell whatever they want, but if the end user finds a way around it too bad. The same should go for DVDs, BluRays and streaming media and yet here we are looking at jail time for bypassing the DRM.

Would you mind providing a citation stating that someone has gone to jail in any country as a result of bypassing DRM for personal use on things they purchased? I am skeptical that this has ever occurred.

Even in the US, which has quite draconian anti-circumvention law under the DMCA, the criminal penalties associated with this behavior only apply to those that violate the statute “willfully and for purposes of commercial advantage or private financial gain”. A person who bought a DVD or blu ray and decrypted it for their own use would not be criminally liable.

https://law.justia.com/codes/us/2021/title-17/chapter-12/sec...

I’m not defending the law, which I disagree with, merely pointing out that “looking at jail time” for non commercial bypassing of purchased BluRay DRM is a stretch.

Good. People who buy things should own the things they buy.

> Where is the right line between "my hardware, my rules" and "my software, my rules"?

There's something obscene about unlocking existing physical features with more money, but there's also our mental model of what ownership means. Imagine you buy a new fridge, and it has an extra compartment that is installed, gets cooled but you have to pay to unlock. No one could ever verify that you didn't rip it open yourself. I don't think anyone would object either.

The current monetization strategies for software favor the corporations. They can withhold service in case of no payment, and they are trying to do the same to hardware. I personally feel we should regulate this as soon as possible, otherwise things like right to repair will simply disappear.

If you opt out of the heated seat package when you purchase the car, that doesn't mean the manufacturer can't add that hardware in a disabled state. That also doesn't mean you own the heating feature after you opted out That's like asking Intel to fix a processor you overclocked

Nah, that's like asking Intel to enable two more cores on a two core processor made from a four core binned chip that they also sell four core processors based on. The only difference is software.

Intel briefly did have a scheme where you could pay to unlock parts of the processor that were disabled for segmentation reasons: https://en.wikipedia.org/wiki/Intel_Upgrade_Service

It was abandoned due to backlash but that didn't stop Intel from doing artificial segmentation, so instead of buying a chip with "3MB" of cache and being able to unlock it to 4MB later, now you buy a chip with "3MB" of cache and 1MB of dark silicon that's permanently lasered off at the factory. I get the objections, but the alternative isn't really an improvement.
