The comment at https://forums.theregister.co.uk/forum/ ... #c_3594547 raises the trademark issue:
We may argue over what kind of a case Redis has here.
But one thing seems to me pure evil. Their new licence has some serious potential to confuse, and to p*** all over two valuable trademarks:
(1) It's already been spotted "out there" referred to as "Apache Common Clause". If Redis themselves sanction such use it's a clear violation of the Apache trademark.
(2) "Common Clause" and the inevitable abbreviation CC have obvious potential for confusion with Creative Commons.
I honestly don't know what we who value those trademarks can do about it. Any lawyers lurking here?
