That would have been hilarious!

Yes, I noticed this also. For all the worries I've heard lately about
lack of commonality/etc it seems like a major missed ecosystem
opportunity to have not invested in an industry standard. From what I
can see fbnic has no hope of being anything more than a one-off
generation for Meta. Too many silicon design micro-details are exposed
to the OS.

I don't know, as I said there is some grey scale.

IMHO it is not appropriate to make such decisions based on some
company wide metric. fbnic team alone should be judged and shouldn't
get a free ride based on the other good work Meta is doing. Otherwise
it turns into a thing where bigger/richer companies just get to do
whatever they want because they do the most "good" in aggregate.
