See, the thing is though, that they kill stuff that DOES stick as well. There's plenty of stuff in the Google Graveyard that was still widely used, with large user base, and they kill it anyway. There's no consistent logic to their killing of products. Sometimes they simply don't want to update it, sometimes it's purely internal politics (G+), sometimes there's just no reason we can find.

What people believe about them matters, not whatever internal rationalizations may or may not have occurred.

Aside from their bad reputation for killing products, they also have a bad reputation for providing next to zero human support services for their products - even if you do pay for them.
