As someone who isn't a corpsec/IT practitioner, though, breaking uBO is literally the most important impact of Chrome's Manifest v3 for me.
I wouldn't mind if Google incorporated uBO as a first-party component in Chromium while applying the restricted policy to all other extensions! Most purported adblockers are crap, if not malware. Pick the best one and restrict the rest.
Unfortunately, I doubt an advertising company is going to incorporate uBO in the browser they provide for free.
I totally buy that breaking uBO isn't Google's goal for Manifest v3! It just happens as a beneficial side effect.
> The moral dilemma here seems to be that Google is unwilling to privilege a good-citizen adblocker like uBO over other extensions; they're an ad company and any explicit step towards promoting an adblocker probably is hard to explain at shareholder meetings
