They don't require your email address to download the filters, so how exactly do they get your address in order to deliver this non-evil allow-listed notification email? It's likely they thought: "What if our existing users/subscribers use these filters? Our own emails will end up archived?! No we can't have that..." and thus they fell into a trap of their own making. Perhaps it's 'lawful evil' to think their own mailing lists are good and everyone else's are bad? Lol.
