Ultimately it seems that everyone loses - the Redis project slowly fades, nobody can use its code on open-source projects any more, and AWS continues on unaffected by the change.
This just shows you have no idea what sspl entails. It states you can use it for whatever you want, but if you want to provide the product as a service, you need to share all your infrastructure code for providing the service.
Its basically agpl with a carve-out for AWS and that is so valid because AWS are vultures. They probably make the most money in the world from postgres but aren't even in the top 3 contributors[0].

Ton case it isn’t clear: I can’t now pick up, say, a module from Redis and use it in a GPL/MIT/BSD-licensed (i.e. open-source) project.
I would suggest making some time to research the effects because it obviously doesn’t work the way you think.
