Broadly, I have no issue with this.

In the first place, it's just a part of the nature of the fediverse that admins are free to manage their instances as they prefer and users are free to choose instances as they prefer, so it's no more significant in that sense than a restaurant not including some particular thing on its menu. It's their choice, and I'm entirely free to order something else or go to a different restaurant.

Specifically, to the degree that it matters (which is likely not at all), this is the decision I'd make too, just because even in a culture increasingly defined by corporate shitweasels, Meta stands out for being especially shitweaselish.

All that said, I keep wondering if it's going to be an issue anyway. The fediverse is a sort of technically and conceptually complex place, and uncharitably, Meta's customer base leans toward the lazy and stupid end of the spectrum.

I can definitely see some likelihood that a lot (most?) of the people who might end up following a link to a Meta-owned instance are just going to get confused and frustrated, then scurry back to Facebook.

We'll see...
