> adblock is /mandatory/ these days
No, it really is not. Ad-blockers are run by a minority of users, and the vast majority simply use whatever browser camne with their PC, or maybe download Chrome. But installing ad-blockers, GreaseMonkey scripts, Firefox extensions and the like basically never crosses the mind of your average web content viewing public. [1]
I'm not sure I'd count the adverts I see as 'abusive' either. Many times I have found ads useful, interesting, curious or (on YouTube videos) worth watching without skipping. Just as with TV and newspapers, yes, there is much crass, unsubtle, and badly created advertising. However, it's all ignorable, and even if a site pops up an inter-stitial advert, I've yet to come across one that I cannot close and move on to the content. Of course, pop-ups that tell me I have read all the free content I am allowed are different, and in those cases I make a choice - do I want to read the article enough to pay for it?
As for wanting GBP 10 per month, I would spend much more than that on physical newspapers (at 50p per issue, the 'i' is one of the cheapest, so that's about GBP 15 per month) so it seems pretty reasonable. And I don't expect my copy of the Guardian to have no adverts because I paid for it, as opposed to reading it in the library. In fact, again, I find the adverts can often be useful and informative, even in such a widely targeted medium as a single newspaper.
