Honestly, I think it's massively significant. For a start off, that's 20 million people, the population of Chile, in one quarter. That's a lot of people regardless of how you slice it.

But more to the point, Meta services - Facebook especially - have reached a point of cultural impact where anyone who doesn't have them can't be talked into getting them anyway. Plus, they're useful messaging services too, because everyone else uses them. Their popularity has become self-fulfilling. The idea of Meta losing more users than it's gaining at all has been frankly unthinkable until recently.
