I read this anticipating a writeup of the downsides of #tvOS (there are several) and worst I read was “#Apple is using its platform to sell you things.” While the increased intrusion of ads hasn't been the best, it's also been minimal relative to what the other platforms do. The #AppleTV isn't perfect by any means, but to say it "sucks" is a lazy take. I've owned several and most have done what I've needed them to do. https://www.theverge.com/23621907/streaming-tv-boxes-roku-amazon-google-apple-nvidia
to offset my Apple sheepishness, I'll list some things that could be better about tvOS/the TV hardware
-a library and playlist setting for screensavers. Let me choose my favorites!
-a playlist feature for content bought through iTunes. Across all apps would be preferable, but let's start small
-the Siri button on the TV remote should be mappable to another function or Shortcut
-FindMy in the TV remote
-bribe Netflix to appear in the Up Next queue
-OS profile integration with third-party apps.
