The rumors of Redis taking on a new Creative Common license ARE NOT true.
Antirez (Salvatore Sanfilippo) writes on his personal blog:
Redis is, and will remain, BSD licensed. However in the era of uncontrollable spreading of information, my attempts to provide the correct information failed, and I'm still seeing everywhere "Redis is no longer open source". The reality is that Redis remains BSD, and actually Redis Labs did the right thing supporting my effort to keep Redis core open.
Here's what IS happening...
What is happening instead is that certain Redis modules, developed inside Redis Labs, are now released under the Common Clause (using Apache license as a base license). This means that basically certain enterprise add-ons, instead of being completely closed source as they could be, will be available with a more permissive license.
