ok, call it theft of services. You used the service but blocked how the creator makes money on the service. Is it really different from someone who runs out of a barber or restaurant?

Yes, the restaurant is not tracking me across the city, and it does not contain malware (although I guess you could get food poisoning).

It would be amorale if these services were not exploiting everyone they can, including the creators.

The better analogy would be, is it okay to walk out on a barber who is spying on your phone, coughing in your face, and won't stop trying to convince you to buy his buddies shampoo or vote for their political party.

yes, the barber doesn't wield enormous power over society duh

the restaurant spends resources (both physical and human) cooking and serving you the meal, likewise for the barber. a better example would be showing up late for a cinema showing so that you deliberately avoid watching the adverts and trailers... which i would guess most people would agree is morally fine?
