I think your line of thinking is flawed. You’re assuming that for one to exist the other has to die. That’s incorrect. tv
sales in 2018 were good. But they don’t have to sale more than everyone else in order for the tv to still be a success. As for exclusivity, you’re forgetting HomeKit. That’s still exclusive for now. Again, I’m gonna bring up Amazon. Amazon has apps and a store. They are still on tvOS. I can AirPlay Amazon Music from the app to my tv right now. I don’t know about photos since I’ve never used Amazon photo storage. I do agree with you that the app will come to other brands. Again, just like Amazon. If you’re tired of me bringing up Amazon then I’ll add Google to this discussion. Google has it’s own devices, but they still have their content on other platforms through YouTube. Since you brought up AirPlay, Chromecast is on other brands too. My Mom’s Vizio TV has Chromecast built in. Is Google’s Chromecast Ultra redundant as result? She still has an tv. making an TV set isn’t smart. In conclusion, this is about content distribution. Plain and simple.
