With this track record I never plan on using a new google product. Now, I will immediately stop using or sell anything I have that is acquired by google. It seems like they're only capable of leaving a trail of corpses of past good ideas.
I think the reason killedbygoogle.com actually exists is because they try to be professional about notifying folks of things they are EoL, and communicate updates along the way.
This is the crux though. You could be totally satisfied with a non-Googly product, but suddenly become a Googly user when Googs buys the successful company. I feel this way about Amazon buying the Roomba company.
Ten years is okay.
Very, very unlikely. The business model was an illusion.
