Earlier quoted context omitted.
Stealing a physical thing = the previous owner can't use it. Copying a thing or accessing a platform = the previous owner can still use or sell it. Even if you consider it unethical access, the comparison to stealing really misses the mark.
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?
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.
