Good points. I don't see anything wrong with these individual open source releases. See my other comments about the larger trend this represents.
"Releasing these things don't give them control over anything that negatively impacts users" and "undermining competitors such as AWS" contradict with each other if you believe competition is good for users. The decision to release something as open source doesn't happen in a vacuum. Open source doesn't automatically make corporate activity morally good or neutral.
