This isn't difficult: TVs should not be "smart".

TVs should be incredibly dumb. They should be screens for displaying stuff. That's it. Nothing else.

No network connection of any kind, no apps, no software beyond that necessary to do basic setup of how that screen works: brightness, input selection, etc.

Seems like an easy suggestion to write, i find more difficult to find a good dumb TV nowadays.

Aren’t all tv dumb TVs if you don’t connect them to the internet?

they still run a bloated operating system that occasionally crashes. The TV can still be smart and at some point I expect them to nag you constantly about not being connected.

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…

Wow, thanks for breaking established standards then...

Perhaps companies should hire more talented customer service representatives who have a technical background instead of continuing to make their products shittier.

Having worked in this kind of customer support, the issue isn't that technician doesn't understand DNS, but rather that the end user frequently hadn't even heard of it. It's a massive pain to troubleshoot something like that remotely when the caller is non-technical. Not impossible of course, but frustrating and requiring a great deal of patience on both ends.

I'm sure that's quite common, but so is the reverse. Almost universally, CSRs have no idea how the product works or have any technical knowledge whatsoever.

I appreciate the article for bringing this to my attention. That being said, and maybe it's just my severe lack of knowledge around DNS, but I didn't walk away with a greater understanding of what is going on and how to fix it (outside of using pfSense).

I'm using OpenWRT and created a guest network which I configured to use certain DNS servers. All of my smart devices are connected to it. How can I check that those devices are actually using the DNS servers assigned at the router level?

There is no justification for bypassing users network settings, and especially doing it for your own convenience. At very least it should be opt in. If you want to violate customer privacy to save money on support, then I don't know why this is worth even discussing.

At this point I don't want things with nonfree firmware in my house.

Nice sentiment, but hard to deliver. You have a dishwasher and a fridge, right? They've been running firmware you don't get to inspect for a couple of decades already. Luckily they don't have network access.

Mine quite happily works as a dumb TV without a connection, and I know many others who do the same. Though I hear stories of TVs being annoying to use without a connection (timing out waiting for a server response that can never come, before falling back to an ad free menu, or just constantly nagging, even while content is playing, about the lack of connectivity).

Yeah I worry about this sort of “annoy the customer into connecting” behavior becoming more common as integrating ads becomes more a part of the business model. Also could connect to open wifi networks in more densely populated areas The real problem will be integrated cellular connectivity with no option to disable.

If it comes with an unlimited data plan, I'd happily buy that TV just to open it up to take the SIM out of it and use it in another device.

You can buy that TV. It still exists. But for now, people are buying smart TVs.

If I use a pihole then Samsung TVs will use 8.8.8.8 as backup (even if not configured)

I had to firewall all dns requests as well...

I assume in the future they will put DNS over https and it will be harder to block - at which point a Linux media player and tv disconnected will make sense...

Doing this because of their crappy spying - sending frames of video to identify what you are playing.
