Unironically, the best streaming box out there is a PC where you can hook up ad block and stream content from independent content providers like Dropout and Nebula using their web-based UI.
We seem to have an economic cycle of enshittification => piracy => people realizing they've over enshittified => goto 10. We were in phase 3 a few years ago, now we're in phase 1 and it's an insane race to the bottom.
The desktop is the best streaming box only if:
- You run Windows because nothing else will let you stream in 4k
- You ignore the absolutely sub-par UI/UX couch experience
And I say this as someone who's been running a media center pc in various forms for decades.
I certainly wouldn't mind being able to block ads on the Apple TV for certain services (by which I mean YouTube), but for services which aren't as aggressively terrible as ad-supported YouTube is, I'm generally fine just making the choice between paying a higher price to go ad-free or putting up with ads. I know some folks are absolutely against all ads no matter what no exceptions, but I'm okay with the notion of "you pay for this by watching ads" if they don't abuse their end of the bargain (by which I mean YouTube).
Also, I watch Nebula on my Apple TV pretty frequently, and Dropout's available there, too.
