The race to replace Redis

The race to replace Redis

The key distinction is that the SSPL is trying to broaden the scope of what must be shared beyond the legal precedents for "derived work".

The AGPL is just trying to be a patch on the GPL so that you can't dodge the "users who receive the binary must have GPL'd access to the source" part by doing SaaS.

The GPL and LGPL already lean on "Yes, some people will tie their codebase in multi-process knots to minimize how much they have to share, but we're OK with that. There's a limit to what's practical, scalable, etc." and the LGPL is narrowing the requirements down from "entire derive work" to "just this library... even if that's an uncertain legal requirement in this implementation language".
