That's funny; most of the anti-ad brigade that I know - including myself - would fall over with gratitude if there was an easy way to pay directly for use of a web site (or similar service).
It can't be that "no one will pay enough", because ads pay *terribly*. Tiny fractions of a penny for an "impression" (that more than likely goes to a bot anyway).
I already pay (through monthly subscription etc) for multiple websites, buy video content from my favourite creators...
