Official Statement: Regarding Mod Usage and Culture

[Catwho]

This is a good, reasonable statement from Yoshi P, and the crux of why Mare in specific was targeted comes down to this, among other things:

The issue is that any mod which makes changes visible to others requires the manipulation or rewriting of game files, which is fundamentally even more problematic and destructive.

Blanket permissions for a third party app to modify your .DAT files passively is extremely risky. Although the app was curated to prevent malicious files or gross stuff from getting shared, it's core functionality still allowed unlimited access to the system data, and all it would take is one malicious actor to spread a virus across thousands of players.

Yoshi P doesn't care what you do to your local computer. But they don't want you messing with other people's computers.
