This is a great demonstration of the danger of BSD + Patents. First it's Facebook using it for a great frontend framework. Now Github is using it for an IDE. It truly a threat to open source.
We're going with Inferno. Vue feels like a better Angular, not a better React. It's not even comparable to React. It's just too clunky.
One pleasant surprise in this Facebook purge has been the discovery of seamless-immutable. It's far easier to work with, especially if you're using Typescript, which makes Immutable an absolute pain.
So in reality what you're saying means: "If you sue facebook with any patent, I’m happy you lose that ability. If you sue any other company other than facebook, I’m happy you keep that ability."
No, I'm not happy with that, but that is also not what's happening here. You're still welcome to sue Facebook if you want, but you'd lose all patent licensed to you in the PATENT file.
I'm also not happy with spreading FUD. Bringing up non-software patent is a strawman.
