If I hacked a server to get content then I would be circumventing payment at it shouldn't be up to me how it responds to requests, I don't own it. Google trying to enforce playing adverts via software running on my property is an unjust overreach. The user choosing what displays on their own monitor is not "circumvention", it's claiming ownership over your computing. Google could choose to verify on their servers if I've paid (in normal currency) but instead their servers act like adverts are an optional donation.
