By this argument going to the bathroom during a commercial break is piracy.

Only you didn’t go to the bathroom. The ad just never appeared.

Chances of you getting up and leaving the room every time an ad comes on: 10%.

Chances of you blocking an ad with an ad-blocker: 100%.

This isnt “someone being offended when accused of piracy”

I think it very clearly is.

This is " People getting upset when an idiot tries to blame end users, instead of holding the people who created the problem accountable"

Whether it is piracy or not has nothing to do with blame or responsibility. You’re still just taking personal offense to being called a pirate and conjuring up nonsense arguments to combat it.
