This says you can't even seriously financially consider suing them or even call them out in any way over ANY of your patents.
If you happen to be a ML/VR/cars company and think "oh, we use React on one tiny website that'd be cheap to rewrite and Facebook uses without paying our 42314 super expensive patents for ML and self driving cars and VR.. should we sue them?" you already are using React patents illegally because you took financial interest in patent assertion.
With that wording taking out the "you (or any of your subsidiaries, corporate affiliates or agents)" part would still cover cases like bankrolling patent trolls that sue.
And 'patent assertion' means:
>A "Patent Assertion" is any lawsuit or other action alleging direct, indirect, or contributory infringement or inducement to infringe any patent, including a cross-claim or counterclaim.
So basically, thanks to that language, being that kind of a company I mentioned above, you could write a blog post saying "WTF, we use React and Facebook uses our expensive shit for free!?!" or even a legal letter to them to stop using patents without getting a grant from you and lose your patent grant already because you are 'alleging' or 'taking financial interest' in 'alleging' or 'lawsuit'.
And other users of software are only protected from you suing them over React patents like in Apache license, Facebook is protected in a special separate way from any patent lawsuit, allegation or even financial consideration of a lawsuit or allegation.
This is very one sided and the reason why I immediately remembered RakNet PATENTS file I've seen back in 2014 when I got hyped over RakNet being open source is because it stuck in my mind how stupid and one sided that patent grant was.
