Right, if you look at the contents of the license in the discussion, they are variants of "if you try to fight us with patents, we will deny you a license/patents".

So you can compete with FB without losing a license. The first blog post you quoted shows a misunderstanding of the license (the word "compete" doesn't show up in the license).

So the correct representation is "If you claim patent infringement by FB, you can lose the license.". This is what the linked comments say, but what your summarised statement didn't properly capture (hence my comment).

Or if Facebook claim patent infringement against you. So what he summarised is right.
