I'm guessing you feel like a bit of a mug for paying your hard earned money to faceless mega wealthy corporation so you want to believe that people who skip the ads without needlessly paying Google are stealing.
Well, they're not. They're just skipping ads.
You don't think it's a little hypocritical to call people stealing when they're just skipping ads automatically? You see a huge moral gulf between clicking a button and having a piece of software click the button? You pirated a bunch of stuff when you were a teen and now you're on your moral high horse over someone blocking an ad or 300?
