If you can spare the money, buy a Smart TV and send it to the FCC accompanied by a letter saying that you have no use for a TV that is invading your privacy and there are no alternatives on the market. If they get enough TVs, perhaps they will take action.

(If you have less money to spare, buy the TV and return it to the manufacturer for a refund, make sure you state the reason.)

By the same logic HTTPS is bypassing your network filtering of every service which happens to have an alternative available over HTTPS. So do you block HTTPS?

I’ve been thinking about installing a proxy with my own root for this reason.

I would not want to use your network if that was the case, and I wonder if you similarly would use someone else's network if it was configured like that. I don't think network operators who provide access to the Internet can realistically expect to control what their users do on the Internet, unless the network operator is also the administrator of those workstations.

The Magnuson–Moss Warranty Act of 1975 ensures that’s not the case in the US. I suspect something similar is true in EU. For the manufacturer to avoid a warranty claim due to a modification or aftermarket part, they must show that the defect was linked to the part or modification. They might have to show that it was caused by , but in any case, if your paint fails prematurely, they can’t say your warranty is void bec…

To get 5 stars by EuroNCAP (and AFAIK EU law demands it too) the car have to call 911/112 automatically if it detect a crash. I doubt you can remove telemetry without also disabling this. If you do the car is illegal.

Interesting point. I wonder if an insurance company can argue the modification made the car lose the safety certification, and in effect the user made the car more dangerous by removing the SIM card, and that it would not pay out for injuries sustained in a crash.

I’m kind of surprised there isn’t an OpenWRT style project out there to provide a replacement OS for common Smart TVs. At least I couldn’t find one. I’m obviously lacking in understanding the massive difficulties such a project would likely face. But it sure would be very nice to be able to replace my TVs firmware with something open source. I don’t want a dongle or extra box or extra remote. There’s a perfectly good…

We've come to expect open replacements of everything, but even OpenWRT didn't start out as an open source project. Linksys used Linux on one of their routers, and was thus forced to release their modifications to the kernel for their device.

Maybe, but my rule is: my home network, my rules. I can’t really do this invisibly anyways: any device I don’t control will get certificate validation errors.

I’m responsible for a bunch of IoT hardware, and every firmware spec I write includes a note on not using the DNS servers provided via DHCP. While sure there are companies explicitly doing this to avoid filtering, at least in my case it’s because a significant proportion of DHCP servers are configured to send DNS to your ISP, and ISP provided DNS is almost universally terrible. They’ll ignore TTLs, rewrite NXDOMAIN r…

If your hardware isn't resilient to network failures then it absolutely is your fault.

I agree, it's also something I would like. I've looked a bit into this regarding Android TVs and found out that most TVs are using similar Amlogic chipsets.

What made me give up on the search for alternative software is that there doesn't even seem to be a place in which any manufacturer's models are even listed, much less anything resembling a community.

> some of these devices are using a sneaky tactic to bypass your PiHole entirely I don't think that it's malevolent on their part. Lots of ISP DNS are crappy. Hardcoding a reasonably reliable one saves them a lot of frustration and unnecessary technical support.

It is because they don’t give you the option to change it. Set the default to what ever you want, but give me the user who bought the goddamn thing the option to configure it how I see fit. You think TV companies are injecting adverts into peoples TV home screens for their benefit, I don’t see a big sticker on the box when I buy the TV “Ads Integrated Directly into Device”

So as a techie I agree with you but as a user I don’t really think it matters. If your device exists to connect to public endpoints and uses mDNS for local discovery then any public DNS server should be fine. All these devices want is a clean connection to the public internet and you’ll never see them officially supporting blocking. At best DNS filtering is a hack that currently works because most people don’t do it and there’s little pressure to work around it. The device is free to exfiltrate all your private data through the connection to the manufacturer’s servers. It doesn’t really need DNS to do it.
