>As I've said before, the story of what's happened to Redis (and HashiCorp stuff) is likely to become a warning to the tech community in general: if an OSS project you rely on transfers control from it's founder(s) to a company, you probably need to consider continuing with a fork from the last open version, because apparently "(try to) monetise popular open source" is the newest way to win the douchebag villain award given to MBAs at VC funded companies.
Or, even simpler, if the project is not contributed to some open source foundation, and does not have copyleft license - it's a trap.
Contributing to a foundation may be a trap too. If you assign your copyrights to a foundation, in many jurisdictions you no longer have control of the code you wrote. That means they could license the code in a way that you wouldn't do.
Yes, but that's where the "foundation" part comes in. If it's one whose charter explicitly states that it exists to support open-source software development, it is legally unable to do otherwise.
