Buy a good inexpensive TV. The manufacturer can make them cheap because they’re losing money and hoping to gain it back with ads and analytics. Don’t connect it to the internet. Get a Steam deck or small form factor PC (Intel NUC or variant) install Linux, profit.
I’ve bought a few small form factor PCs, and again Steam Deck works great, for $300 and then a great TV. And I don’t have to put up with any ads, any crap applications that barely work, it’s just browsing ANY website I want, playing ANY PC game I want. It’s honestly the best outcome and I’ll never go back at this point.
Don’t let yourself accept the subpar TV applications that are just a website with awful frontends, that run like shit and that the companies creating these apps have 0 incentive to make properly because their app isn’t there for a good experience. It’s there to track you, just like the TV.
