First, it doesn't even mention that without an adblocker your being tracked all over the place by advertisers. (A practice that is btw clearly illegal in many countries, even if they haven't explicitly wrote it into the law yet.)
Second, but this is more subjective, I have a rather different experience with turning off adblockers. Almost every website becomes several times (!) slower, and is full moving distractions trying to get my attention. Sorry, I can't read that way offline, and I won't read that way online. Only when advertising stops disrupting my experience and is only passively present (like it is in old-fashioned dead tree publications) will I turn off the adblocker.
I the mean time, I only make exceptions for sites that a) understand I have no obligation to download their ads, and ask nicely, and b) are very careful about the ads they put on their site.
