Adblock usage has been creeping upwards every year. It’s only the fact that most people use mobile devices, that slowed its growth.

Now, extensions to block ads are mature on mobile.

On some sites I run, I see 60% blocking on desktop, 10% on mobile. If it hits 60% on mobile as well, then the ads would cease to be profitable.

Do you have a source for those numbers? By your argument, advertising should already be unprofitable on desktop, which seems unlikely.

It's a site that they run, they are the source for those numbers.

A quick google says somewhere from 20%-40% use adblockers. 60% sounds high, but depending on the website, I can see it. For example, I bet at least 60% of visitors to gnu.org are blocking ads and/or trackers.
