I wish Redis and its ecosystem was 100% open source, but I also wish for a pony. I applaud Redis Labs for not being one of the companies (such as MongoDB) that appears to be intentionally trying to muddy the waters by blurring the distinction between open source and proprietary software.
Consider this quote from RMS, in Copyleft: Pragmatic Idealism:
> I make my code available for use in free software, and not for use in proprietary software, in order to encourage other people who write software to make it free as well. I figure that since proprietary software developers use copyright to stop us from sharing, we cooperators can use copyright to give other cooperators an advantage of their own: they can use our code.
