For everyone saying "Google is pushing canvas usage to kill ad-blocker effectiveness", maybe, but most of Google's ad revenue already works around ad blockers.

For everyone saying "Google is pushing canvas usage to kill ad-blocker effectiveness", maybe, but most of Google's ad revenue already works around ad blockers. Most of their ad revenue comes not from their display network (ads that they serve on other ppl's property), but from showing ads on their own properties. Only ~13% of their revenue comes from ads displayed on properties they don't own: https://finshots.in/infographic/breaking-down-revenue-streams-of-google-the-alphabet/ https://finshots.in/infographic/breaking-down-revenue-stream... And "only" ~25% of users use ad blockers, so ad blockers likely only hit Google's total revenue by ~3%. Ad blockers mostly work by blocking known display-ad-serving JS scripts, that ppl include on their page. Ads within Google search, Gmail, YouTube (and big non-Google advertisers like Facebook, Twitter, Reddit), don't use this approach, the ads are much more built into the page (embedded in product JS bundles, or simply returned by the backend from Ajax calls, mingled in with non-ad data). These ads are really hard to block, regardless of whether the page is a traditional web document, or uses canvas. Blocking them basically involves parsing the page and looking for things you think are ads, which is incredibly difficult to make work reliably over time, so nobody really bothers, and that's true regardless of canvas vs. traditional web document.
