Maybe instead of hoping for a lawsuit just stop buying shit google makes. They’ve repeatedly dropped whole product lines on short notice, and even the Android phones they have produced have sometimes had pathetically short supported lives.
So you buy something else like Nest, and then google buys the company and removes your functionality anyways.
That is, if vendor lock in will even allow you to get some other product without having to replace every device in your home (and hope this new vendor doesn't do the exact same within a few years).
Fair consumer protection regulations are necessary in modern society, the "vote with your wallet" strategy doesn't scale.
The Google Play store is the chokepoint for Android. I maybe can get roughly the right functionality via an alternate app repo, but there's always going to be some mass consumer app that's important and unsupported, or some glitch or incompatibility. There ought to be law....
