How does using react support facebook though?

[nanis]

By providing Facebook with a "reserve army of developers trained in and willing to use the framework they use to build their stuff".

Does it still hold true, that by using React or any other tech that comes out of Facebook, you relinquish your right to sue them?

No, it's since become MIT https://github.com/facebook/react/blob/f320ef88f51fbdc5aba38...

At the very least, it results in people filing bug reports and feature requests which may in turn result in their products being more reliable, faster, etc.

I don't know what their policy on accepting code contributions from third parties is, but the prospective value of those contributions should speak for itself.
