Adblock extension for Chrome and Safari sold to unidentified buyer, joins Adblock Plus' Acceptable Ads program

Context & Ripple Effects
The sale lands about a month after Adblock Plus launched its own free browser on Android and iOS, part of parent Eyeo's push to control the full blocking stack rather than just filters. With the independently developed Adblock extension for Chrome and Safari now sold to an unidentified buyer and enrolled in the Acceptable Ads program, the two best-known blockers converge on the same commercial model: default blocking with a paid whitelist.
First-order effects
- Users of the Adblock extension get the program's 'acceptable ads' switched on by default, changing the product they installed from an all-out blocker into a filtered one.
- Eyeo's Acceptable Ads list gains the reach of a second major extension, strengthening its position as the gatekeeper deciding which ads pass.
Second-order effects
- Other independent blockers face a fork: join the whitelist economy or compete on stricter defaults, while publishers gain a sanctioned route back into blocked inventory.
- An unidentified owner controlling both the extension and its filter updates raises supply-chain questions of the kind that surfaced later when researchers found 295 Chrome extensions with over 80M users inserting ads into search results.
Third-order effects
- Ad blocking is institutionalizing from user protest into intermediation — a pattern Google formalized in 2019 when Chrome shipped its own ad blocker adhering to Coalition for Better Ads guidelines, moving filter decisions from extensions to platforms.
- If whitelisting becomes the norm, the durable business sits with whoever operates the acceptable-ads registry, not with the extension developers who built the audiences.
The trend: Ad blocking is shifting from a user-side boycott of advertising into a paid whitelisting business, with Eyeo's Acceptable Ads registry as the template platforms are now adopting.
