There isn't much of a difference between digital media and "services." We'd all agree it would a dick move if I walked out of barbershop without paying, even if the barber didn't have any other available customers at the time.

You have robbed them of their finite time, by sitting there, getting your haircut, and then walking out.

A pirate however, does not deplete any of the provider's resources. They don't use computational or transactional resources.

If I used my haircut-robot to create a strand-for-strand identical hairstyle as the one you paid your barber for, is that me stealing from your barber?

In many jurisdictions this isn’t theft either, and often the police can’t do much about it. Technically it counts as non payment of debt, which would have to be recovered by a civil action.

In practice they’ll just bar you from the premises.
