Nest itself did this too. My gen 1 (pre-Google) Nest did forced OTA updates. Once or twice it bricked itself; fortunately it was still able to receive updates and Nest corrected the problem.

Then they couldn't resist fiddling with the UI. Every new update changed the UI such that I had to relearn how to operate it.

That was the last straw, so I disconnected it from my wifi and just used it as a standalone thermostat.
