React is just one example, Facebook does a lot more engineering and releases it to the public than React.

I know I could just use and promote React without using and promoting Facebook-The-Platform. My argument was more around that by using React and promoting it, aren't I indirectly promoting Facebook then? Same goes for Microsoft or any other company that has a "good" side and a "bad" side. How can we support the good side without supporting the bad side indirectly?
