This is the best summary I could come up with:

More than half of Americans are using ad blocking software, and among advertising, programming, and security professionals that fraction is more like two-thirds to three-quarters.

More striking are the figures cited for technically savvy users who have worked at least five years in their respective fields – veteran advertisers, programmers, and cybersecurity experts.

"People who know how the internet works – because they work as developers or in security or in advertising – they've all over the years decided that it was a good idea to use a tracker blocker or content blocker or adblocker, whatever you call it," said Jean-Paul Schmetz, CEO of Ghostery, in an interview with The Register.

"It's pretty unanimous that people who work in this industry and know how these things function want to protect themselves."

Schmetz said one surprising finding had to do with the extent to which people trust various companies that collect online data.
