Cancel culture or not, people are allowed to tell other people they know that something is happening, and those people can decide for themselves to patronize the business or not. To call it a threat is really exaggerating.

The headline makes it sound like people are phoning in bomb threats and violence, which doesn't seem to be happening at all.

Honestly, I think the business owner should have ignored these weak "threats" altogether. It doesn't have anything to do with coffee and it's unlikely they'll get any business because they use AI, so it can only hurt them.
