Manifest V3, Google Chrome’s soon-to-be definitive basket of changes to the world of web browser extensions, has been framed by its authors as “a step in the direction of privacy, security, and performance.” But we think these changes are a raw deal for users. We’ve said that since Manifest V3 was announced, and continue to say so as its implementation is now imminent. Like FLoC and Privacy Sandbox before it, Manifest V3 is another example of the inherent conflict of interest that comes from Google controlling both the dominant web browser and one of the largest internet advertising networks. Manifest V3, or Mv3 for short, is outright harmful to privacy efforts. It will restrict the capabilities of web extensions [...] like some privacy-protective tracker blockers [...] Google’s efforts to limit that access is concerning, especially considering that Google has trackers installed on 75% of the top one million websites. Firefox maintains the largest extension market that’s not based on Chrome, and the company has said it will adopt Mv3 in the interest of cross-browser compatibility. [...] As for Chrome’s other justification for Mv3– performance– a 2020 study by researchers at Princeton and the University of Chicago revealed that privacy extensions, the very ones that will be hindered by Mv3, actually improve browser performance. [...] "A web browser is supposed to act on behalf of the user and respect the user's interests. Unfortunately, Chrome now has a track record as a Google agent, not a user agent."

Gli adblocker danno molto fastidio sia a Mozilla che a Google, sopratutto sui browser mobile. Tant'è che gia da oltre un anno, molte utilissime estensioni di questo genere sono state bandite da Mozilla sul mobile. Eccetto uBlock Origin (che Mozilla non potevano proprio censurare senza perdere la faccia) quelle rimaste sembrano selezionate per non disturbare troppo il tracciamento ma lasciando agli utenti più sprovveduti l'illusione di essere protetti e tech-savy. Sarebbe interessante ragionare su come un sistema antitrust dovrebbe o anche solo potrebbe impedire queste pratiche. Non è nemmeno questione di interoperabilità: il nuovo framework taglia le gambe a tutte le estensioni privacy oriented in un solo colpo. Ne si può dire che sia questione di concorrenza, perché Google non produce ad blocker. Dunque? Giacomo
