Amigo - the corpos already know. They also know that anyone who hates ads enough to install and maintain ad blockers is also not going to click on ads. They’re wasted impressions. The amount an advertiser pays to put an ad in front of you is a rounding error compared to the amount they pay when you click.

When I worked at G I had a Linux laptop. It came pre-installed with Firefox and uBlock origin in addition to Chrome.

If Google is distributing Firefox with uBlock internally to employees they know about ad blockers.

It’s similar to how scam emails always have egregious spelling errors: they’re trying to select out the people that won’t fall for the scam.
