The race to replace Redis

If the SSPL and the AGPL are equivalent (hint: they aren't), then only one of them needs to exist.

There is a line in terms of impingements upon freedoms every open source developers is willing to tolerate. For many, AGPL is close to that line and the SSPL is on the wrong side of it.

There are of course also concerns that SSPL requires legal authorities outside of copyright law.
