Is this not a good idea? It makes average users more selective about what content they are sharing, and reduces scam/bot content that can currently spam post links for free.
Facebook actively courted publishers so they'd post links to their content on their pages. Now they want to charge them for the privilege.
Very few spam/scam posts I see rely on external links. FB is an all in one scammers paradise. This just seems like a transparent attempt to keep people on platform.
This is for Facebook Pages, not for users. Average facebook daily user can keep posting 35 links a day to their favorite slop site.
If it is for that reason and not a money squeezing/enshittification thing, it seems like a big admission their feed algorithm doesn't work.
Facebook knows what you want to see, because you can follow pages and individuals. They choose to show those scam/bot posts to you anyway. This isn't to fight bots.
