Assuming some users know how to control a computer (some claim they do e.g. those working in IT), why would they tolerate this annoyance? It must not be that bad or else they would work around it, using their professed skills in controlling computers. Or maybe there are other reasons? How many technical users are complaining about advertising while at the same time assisting advertisers to put their marketing cruft on the web?
