Personally, I do not disagree that YouTube is worth paying for. But I have reservations because I believe their parent company (Google) already profits tremendously in morally objectionable ways. Thus, I try to avoid giving them my business as much as possible.

Unfortunately, the reality is Google (and YouTube) are practically impossible to compete with in all things data.

To play devil's advocate: you say you use adblocker (I assume you use it on sites other than YouTube) -- but why? Because the modern web is practically unbearable without it? But is there not an implicit contract when you visit a website and consume their bandwidth, that you view the ads? Are you not, in effect, stealing? Sure, advertisers don't have the right to your attention, but don't the content creators have the right to your financial support?
