I just wanna my Apple TV to run Safari browser.
My conspiracy theory on this is that Apple knows a lot of their casual users might find that an Apple TV w/ Mouse/KB (if enabled) is all they need for computing (all cloud/web based)
Those folks are now buying much more expensive iPads and MacBooks
In an ideal world, Apple would do this and make their platform the go to place for a casual web machine..
But... "hundred dolla bills y'all"
Also -- I think they are just lost on tvOS and don't really know what to do with it.
When the whole plan of them having their own YouTubeTV type of thing never happened they got off track. The product has basically languished from then on as a very overpowered and overpriced streaming box.
