There is nothing illegal about packaging Redis, or other open-source projects depending on it, irrespective of jurisdiction.

And Arch has no customers to worry about if they accidentally depend on a package that restricts closed-source commercialization, not that it's a distro's job to pick on that anyway. Commercial entities are supposed to have a process that checks the licenses of all dependencies. If you know how to reliably avoid AGPL, then you know how to reliably avoid RSAL and SSPL.

And I'm liking the cognitive dissonance of dissing Redis while praising Red Hat 🙂
