Might be, but that does illustrate one of the problems with ad blocking: those who use it often forget that they're hurting real people, including those who had nothing to do with the ad campaigns. The best thing you can do to get rid of obnoxious ads? Complain -- these kinds of ads sometimes show up unexpectedly in the rotation, and sites can frequently ask to have offending campaigns pulled.
If a website wanted to make difficult to block ads that were tolerable to most users, they'd just serve some static image files from their own servers and get rid of all the flash and other crap that makes sites an utter pain to load.
There are plenty of alternatives to the current status quo and I hope now that these blockers are becoming more widespread that we'll see the industry change. Napster made the old music business obsolete and no amount of dragging their feet helped. Eventually they changed and everyone survived.
