This is already extremely common. For example, my TV uses some sort of Roku-branded OS. They literally have ads on the home screen when you first turn on the TV. It's something I've struggled to work around, and eventually gave up. I just kind of avert my eyes until my Apple TV kicks in.

I feel like this should be illegal. It's kind of like billboards on the side of the road, it's something I never want to say but it's forced upon me. I bought your product, why is it allowed that you can just throw ads on it? I understand they sometimes sell these TVs at a slight loss to make up for that, but I feel like they should be required to sell the same TV without Ads for the same 3% margin added on. I bet most people would pay for the latter if it was provided.
