Thanks for the links to the patents issue on the React and other Facebook ‘open source’ tools.
As a company that makes money off its Meteor application, and with some real innovation under the hood, we couldn’t risk it. If it’s not MIT / BSD / Apache, we don’t touch it (unless we can purchase an outright license, IF it’s something we really need and can’t find alternatives).
I have commented about it here: React - Facebook patent - a problem? - #30 by khamoud focusing on the intent / interest which for us makes it crystal clear we shouldn’t get even close to it until the license becomes cleaner.
