hereunder

Edit downvotes, well maybe the text of the clause will help > The license granted hereunder will terminate, automatically and without notice, for anyone that makes any claim...

Seems to me the more problematic part is clause b: The license granted hereunder will terminate, automatically and without notice, for anyone that makes any claim (including by filing any lawsuit, assertion or other action) alleging...

The license granted hereunder will terminate, automatically and without notice, for anyone that makes any claim (including by filing any lawsuit, assertion or other action) alleging (b) that any right in any patent claim of Facebook is invalid or unenforceable.

However, if you read closely, the last paragraph starts out with: >The license granted hereunder There isn't actually any license granted after that clause (it occurs before this clause), so I'd argue the entire last paragraph is meaningless puffery.

>Notwithstanding the foregoing, if Facebook or any of its subsidiaries or corporate affiliates files a lawsuit alleging patent infringement against you in the first instance, and you respond by filing a patent infringement counterclaim in that lawsuit against that party that is unrelated to the Software, the license granted hereunder will not terminate under section (i) of this paragraph due to such counterclaim.

I don't think ambiguity was the problem with the old version, but this was: "The license granted hereunder will terminate...

"The license granted hereunder will terminate, automatically and without notice, for anyone that makes any claim" For anyone who makes any claim.

They are not just litigation defense like the ones from the Apache Foundation: "The license granted hereunder will terminate, automatically and without notice, for anyone that makes any claim [...] alleging [...] that any right in any patent claim of Facebook is invalid or unenforceable."

The linked document says: "The license granted hereunder will terminate..." that could be read to mean both licenses, the copyright one and the patent one, but the most natural reading, particularly as they are in separate files, is that it is referring solely to the patent license.
