I mean, they do. DMCA “requests” go to the ISP and the customer and that is just as easily a starbucks as it is a residential home.

And I speak from (my niece’s) experience: Cops have no problems walking up to the counter in the middle of lunch, forcing their way past all the customers, and very loudly telling the pimply faced teenager that they need to speak with the manager about a child porn investigation. I was not privy to the actual discussions but… they lost a lot of business that day and, when I go back to visit family, I still hear that coffee shop referred to as “the pedophile place”.

This is WHY any sane public wifi is behind a captive portal and likely has a LOT of security and spyware running in the background.
