What I find questionable is that the sites by their 'modus operandi' shows little or no responsibility for their part in it all.
First they let any and all obstructive ads display on their site, then when the users had enough and get an ad-blocker, the users are the 'problem'???
Mind my language, but dang, keep a sober attitude towards it will you? It is the Ad-industry and web-sites which are the real problem as they both had years to evaluate this, but both parties were to ignorant to read the writing on the wall for reasons I will not speculate in.
When the situation was allowed to come this far with very little being done to rectify it, I perceive the whole resulting scenario where the internet users are to blame as nothing but whining.
As a little humoristic view, here is a flowchart to visualize a little and I can't help thinking they are somewhere in the bottom middle loop desperate for someone to blame, but as much as it is said; trying to blame users for what both parties really are responsible for is not working...
