Fact is, they have good reasons to. Lemmy likely was threatened by a larger industry that could've thrown millions of dollars around in a court to get Lemmy taken down.

When it comes to losing the community or blocking a couple communities, it's an easy choice. In summary, they're just trying to save the website by avoiding future lawsuits, and these communities still exist but can't be accessed on Lemmy itself.
