Being cynical here, but there's always option 3) you forgot: they might want to ride the Enterprise NoSQL wave, make redis fully proprietary, fire you and then do the lawyer stunt outlined in the original article, possibly even trying to not just get the trademark but also the copyright on the code.

I'm not saying they are going to do that, it's just a third option that's possible in my opinion and which had just become a bit more likely now that they have shown how they are willing to do with projects they own^Wsponsor.
