chrisg, 
There goes Redis:

This is such a mess, it is hard not to feel angry.
Briefly - the cloud providers are definitely a huge issue. They are the vampires of the software community and the root cause of many of our problems.
But redis didn't go against them. They went against the community that made them grow. Same like Mongo, Neo4j.
And as @jenniferplusplus said - don't sign CLAs. They are a big part that let moves like these happen.
