No, it's still tiresome. At least to me it is. In this thread alone Apple should buy Disney, Netflix, Sony, Viacom CBS, and probably some others I missed. I'm pretty sure you can't go to a single story on MR about this type of subject matter without multiple "Apple should just buy..." comments. Most of the reasoning typically boils down to Apple has huge cash stockpile so they can buy whatever. The "logic" tends to go down hill from there.
As for Sonos... eh. They don't really bring anything Apple couldn't do for themselves. Apple can already do (limited) whole home audio with the HomePod and expanding the HomePod line up with a variety of components would only increase it's reach. Sonos is not really a big player in Home Theater so I don't get the connection there.
I personally think the AppleTV is going to be a dead man walking in the very near future, and the ATV app is going to fire the bullet. I think not tying the service to the AppleTV hardware was the smartest move Apple made regarding ATV+. ATV+'s thrust into the living room is probably going to be spearheaded by the
ATV app on TV's, Rokus, and all of Apple's other devices. Apple says the app is also coming to other devices. I'm guessing the upcoming consoles from MS and Sony will have an ATV app.
