> Manifest V3 will stop this by limiting what Google describes "remotely hosted code." All updates, even to benign things like a filtering list, will need to happen through full extension updates through the Chrome Web Store. They will all be subject to Chrome Web Store reviews process, and that comes with a significant time delay.

So the author can't think of any other reason for this change other than to "slow down ad blocker updates"

Well how about stuff like this: https://github.com/extesy/hoverzoom/discussions/670

Where an extension dev details offers to "monetize" his extension and basically perform a bait and switch and make it malicious.

Pretending that V3 is all about ad blockers is more than a little disingenuous.
