From the article, 27% of users; this is higher than I thought, and not negligible anymore.

Note: I tried a few google search to find accurate data, but it goes all over the place; is there an accurate estimation somewhere?

Finding out if someone is running an ad blocker is not easy. After all a good ad blocker tries to be stealthy about it.

There are plenty of websites that detect that I'm using an adblocker. It's mildly annoying, but then I get to decide if what I was about to read was worth it.

Most of the time it's journaldemontreal.com (and other Quebecor-related websites) that prevents me from reading their articles with my adblocker. Which is a blessing in a way, because it's basically a glorified tabloid with a lot of articles of dubious quality.

I'm on Firefox with both AdBlockPlus and uBlock Origin.
