It's like hard slap straight in the face. They changed license because they perceived that multibilion giant(s) feasts and earn money upon their work and gives back not that much.
In return giant just slaps
I’ll never understand why we collectively wag our fingers at individuals or companies that try to keep the likes of Amazon from building a profitable service off of their hard work then contribute back little-to-nothing. Would redis, mongodb and dgraph have even considered alternate licensing if companies like Amazon had thrown them a minuscule amount of funding and patches? We can’t know because they didn’t. And then we sneer at them for having the audacity to try to stay open but stop these giants from using them and throwing them away.
