Creators have stated that while their viewcount is down their ad revenue is not - but a lower viewcount still presumably hurts youtubers for in video sponsorships, and if some genres of video have a higher portion of users with blockers, that probably hurts that entire genre in the algorithm. It sounds like viewcounts are returning back to normal though.
not really, because watching videos without ad blockers would be quite painful
When channels are claiming their view count is dropping 30% but still earning the same amount of money, that would indicate that they are losing out on 30% of their potential revenue because of ad blockers.
Creators can now though, knowing how much they make per view on avg, and slot in the avg number of view that were missing, work out how much they are missing out on due to ad-blocking.
For large creators, it's likely in the tens of thousands of dollars per video assuming most are seeing the same ~20-25% drop.
Eventually the "morally pure" internet will need to reconcile it's habit of not compensating creators.
If I were Google I wouldn’t be that worried about, like, Firefox users with ad blocking addons, or pihole users. But I’d be a bit worried that Apple might take a harder stance against ads, in their browser.
