Absolutely. There is absolutely nothing to be ashamed of. Nothing. Not a single thing.
I make it a point to recite this mantra in every single ad blocking thread I see:
Our attention is ours.
It's not theirs to sell to the highest bidder.
It's not currency to pay for services with.
It's part of our cognitive functions and it's absolutely inalienable.
They are not entitled to our attention.
Our minds are sacred ground. They do not get to violate it for profit.
They do not get to insert brands and products into our minds without our consent.
To do so is mind rape.
Advertising is therefore a form of violence.
Ad blockers are therefore legitimate self-defense against this violence.
