If you only care about contributing improvements, no, it doesn’t matter.
If you want to at least be recognized as an author, and be able to say “I made this”, the license opposes that.
Waiver of Rights: You waive any rights to claim authorship of the contributions […]
I don’t know how they intend to accept contributions though. I guess code blocks in tickets or patch files? Forking is not allowed, so the typical fork + branch + create a pull request does not work.
Also, this isn’t even compatible with copyright law in some countries. I.e here you can’t give up authorship at all; you can only grant an irrevocable, perpetual license (that might even prohibit you from distribution yourself and such) but you’ll always be able to say “I made this” no matter what their license says.
