There's only one reason for anyone, or for me, at least, to choose Android, and it's the only reason I've consistently chosen Android from the very first Google Developer Phone: It's more open.
So, they don't want me to even have that one reason to keep choosing Android, I guess.
the question isn't whether you still have a reason to choose android - the question is what alternative do you have but android (or iOS).
If my phone is going to be locked down anyway, I'm choosing the platform that at least pairs with my AirPods properly and doesn't get me weird looks at social events.
Google is really stretching their goodwill with this one. The ability to sideload and debug my phone is the only marginal benefit to these janky Java relics. If that's gone, no reason not to switch to a wholely better platform.
If I don't get weird looks at the kinds of social events where everyone else has an iphone, then I have failed at life. I can think of no greater horror than to be seen as uninteresting.
