I agree that it will probably not influence the growth of crypto overall, but not caring about the news is not a smart thing to do. This is still Facebook we are talking about. In terms of reach, it is rivalled by no other service save for TV and is a giant economic powerhouse. Sure it won't stop the growth of crypto, but it will most definitely shunt its speed of growth. Maybe not by much, but still a respectable amount.
I myself only decided to finally take the plunge into crypto after a rogue video on XRP poped up on my Youtube feed.
