Way late to the party, but @OP it just boils down to some Karens who get upset that their little oasis isn’t theirs any more.

The same attitude where “Your kid can’t practice piano, MY KID is the piano player!” Or “how dare you buy a Tesla! I bought one first and now you’re just trying to take away spotlight!”

As with any crazy animal encountered in the wild, the best policy is to back away slowly. And wash your hands. Maybe spray it with water.
