I would definitely be less likely to buy food/drink from a place with AI ads (because I don't trust that what they're advertising would correspond to what they're selling), but I can't imagine threatening someone over it.

im like you, simply out of apathy. but i immediately thought, "if were the coffee shop owner, would i rather experience a silent decline in business or face public outrage but have an opportunity for redemption?"

ive been called enough mean names by friends and strangers id much rather be called some more mean names in order to become aware of what i could do to win back some customers

I would once again like to point out that the "threat" mentioned in the article is someone saying they'll talk about what the shop owner did with their friends.
