The argument that "Google still controls Chromium so it's not good enough" is exactly the kind of FUD I'd expect to back up this kind of psyop, too.
His point was that there isn't enough time to again develop Firefox (or ladybird) as a competitive browser capable of breaking the Chrome "monopoly". I don't know if I really agree.
Evidently, Google feels like the time is right to make these kinds of aggressive moves, limiting the effectiveness of ad blockers.
The internet without ad blockers is a hot steaming mess. Limiting the effectiveness of ad blockers makes people associate your browser (Chrome in this case) with this hot steaming mess. It is difficult to dissociate the Chrome software from the websites rendered in Chrome by a technical lay person. So Chrome will be viewed as a hot steaming mess.
I guess we will soon see if people will stay on Chrome or accept the small initial pain and take the leap to a different browser with proper support for ad blockers. In any case the time is now for a aggressive marketing campaign on the side of mozilla etc.
I am in no way affiliated with Google. So if you still think this is a PsyOp, please consider Hanlon's Razor:
> Never attribute to malice that which is adequately explained by stupidity.
Although, please also consider that Hanlon's Razor itself was coined by a Robert J. Hanlon, who suspiciously shares a name with a CIA operative also from Pennsylvania. It is not unimaginable that Hanlon's Razor it in itself a PsyOp. ;)
I can't imagine what hoops Google would have to jump through to block third parties from integrating their own ad blockers. You don't need MV2 for that AFAIK.
Probably for Google the easiest way to keep 3rd-parties from integrating native ad blockers is through licensing agreements for new code/modules in chromium. At this point there will be a fork of chromium, taking the latest non-adblockerblocker-licensed version and the two versions will start to diverge with time.
My point however was not that Google might one day block 3rd-parties from integrating ad-blockers in their own chromium variant. My point was that building on the chromium-base will improve the chromium-base, which will improve Chrome and additionally allow them to claim they haven't monopolized the browser market.
Genuine incompatible-by-time forks of chromium are not in Google's interest and thus Google needs to balance their competing interests of maximizing ad revenue, but also keeping Chrome a high-quality product and not being seen as a browser monopolist.
