Cory Doctorow, writing for EFF about the history and present of adblocking:

The rise and rise of ad-blockers (and ad-blocker-blocker-blockers) is without parallel: 26% of Internet users are now blocking ads, and the figure is rising. It’s been called the biggest boycott in human history. It’s also something we’ve seen before, in the earliest days of the Web, when pop-up ads ruled the world (wide web), and users went to war against them.

Fascinating. I’d never heard of adversarial interoperability before.
