The ad blocker thing feels like the user rebellion over copy protection in the late 80s. Disks used to have bad tracks that made it impossible for the OS to copy them. It wasn't hard to write utilities to copy the disks, so it didn't really work. One day the users decided, en masse, all the more impressive because this was before the web, no more. They cut up the disks and mailed them back. Right away we knew it was over. You can't be in business and be so hostile to the people who love your product. It just didn't work.
