I meant "free" as in "beer". I am aware that SPSS isn't open source, but as usual, there's nothing stopping the last open source version from being forked and maintained. You need to go through the code and documentation and s/Redis/Libredis to avoid trademarking issues, but there's nothing stopping the industry from continuing open source development and maintenance. If the industry comes together, and Redis only sells limited copies, as I would expect from a previously free product, it will effectively look like Redis is a fork of its open source version, not the other way around. If the industry doesn't (because that would require time, money, and effort), I can't say I have much of a problem with the situation, because apparently people were using the Redis devs for free work and not much else.
