I have determined that relying on Google products is just a bad idea. I once included Google's V8 engine on a project I was working on. Google would regularly make breaking changes with no documentation . Developers were required to figure out the new interface on their own... occasionally you would find someone else on a forum somewhere who had reverse engineered it, saving you the time. Sure, Google can do whatever…
For the short term foreseeable future, there's a continuing larger number of people coming in to the field who've not yet been burned, and will continue to choose Google libs/projects without that experience. Google doesn't seem to need to worry about burning a few bridges here and there, yet. Maybe they'll need to adapt in the next 10 years?
