I don't think "Meta" will die, but "Facebook" might... Meta being the parent company, Facebook being a sub company... As long as Meta keeps something running (I am going to guess that Facebook Infrastructure might be spun out and used as a separate entity) they may have other stuff as a post Facebook project... This whole "Metaverse" thing is one of those that might end up replacing Facebook... then again, both could die and something else takes over... [Edit] Doesn't directly answer your question... but if internal dev still need React, they will keep it around...

Facebook still has billions of users. It's a very very long way from losing users for the first time or losing stock value to dying altogether.

It will certainly be a regional phenomenon. Facebook will become blocked and/or uncool in some country and it will spread. Also generational, the younger you are the more tolerance for constantly trying new things will be. I don't see my mid sixties mother ever abandoning her facebook quilting groups or her chats with her cousins, but her kids and her grandkids will eventually move on to something else. Just like AOL it will shamble on shedding engagement (user numbers can be juked and what constitutes an 'active user' in their shareholder reports will constantly be relaxed to prop up their egos) until one day it's a footnote.
