Reasonable people realize that unforeseen things happen, and might empathize with someone being targeted by a criminal enterprise a bit more than someone who just forgot to pay the electricity bill.
There is an entire movement in Sicily dedicated to highlighting and frequenting businesses that refuse to pay protection money, because in the past, paying was the norm.

Since that's not the kind of society I want to live in, I'd rather stand firm behind a company that refuses to deal with criminals. If companies give in as a matter of convenience to retain customers who turn a blind eye, that will only make the criminals stronger.
Now, certainly, there are measures they can take to mitigate the problem, but with all the things to do in a business, I suppose it's the kind of thing that might not be on the front burner until it happens. There are all kinds of bad, destructive things that could happen in the world, but if you spend all your time worrying about what could happen, you won't have a viable business. It's a tricky balancing act, and I'm willing to cut some slack to someone being targeted by criminals.
