I have no problem with none intrusive ads as running my own website I know how important it is to have ads when your giving your content away for free. But I don't force anyone who is using an ad-blocker to disable it before they can get to my website as I know how annoying this is myself. Instead I have back-up revenue option in the form of affiliate text links to Amazon products which aren't blocked by ad-blockers and users generally don't mind them.
If people running ad-blockers are going to be getting redirected to a paywall it sounds like the next big thing will be a paywall redirect blocker plugin.
