So far, the Linux Foundation, from what I have seen, has pretty darn good track record of keeping the projects under its umbrella open source, even going against corporate sponsors to do so. For a recent example, see the recent NATS tuffle. (And I should.recognize that Synadia, finally, did the right thing and backed down).

To add to this, I've experienced all sides of the LF and they are the only organization I trust at this point. Donating a project to them is A Good Thing.

There's bureaucracy of course but the mission is clear. Highly recommend working with them in any capacity.
