We're 'so damned negative' because this is yet another anti-feature that removes control from the owner of the device.

If I don't want to update now, I shouldn't have to. My device, my rules.

And this feature encourages bait and switching: free app is no ads and free, and then at update+1 gets malware installed for free on forced update. We've already seen this with optional updates - only now they won't rely on tricking the user. They'll just update.
