People typically associate piracy with actions that can land individuals in legal trouble due to it being law breaking. I don't know that there is a country yet that sentences people for using Adblocker. Even the FBI recommends it.

Like I can see how companies don't like people consuming their service without seeing ads, but this isn't people copying or cracking and stealing account credentials to get access to something that is paywalled like some Netflix account. This is a flaw on their end and people are accessing it legally.

It's like some drive in theater getting mad someone who lives across from there can just watch movies from their backyard without paying and then saying they are committing piracy. They aren't sneaking into a theater.
