Junk pages with no useful content do not tend to survive, hence that is not a valid comparison. Just as you "install and use repeatedly" apps that are useful, you only revisit pages that are useful. So, the relevant analogy is between a page of some value and an app of some value. If ads weren't a problem on pages that fit this description, then we wouldn't be having this discussion. Annoyance is annoyance in any context, even if it stops short of outright malice.
