I don't see any technical specification i the article, but if they inject the ad at the start of the video, making it part of the video itself, would make possible to just skip it using video controls. To avoid user skippin ad thru video controls there should be client-side script blocking it, so an ad-blocker can use this to tell apart an ad from the video itself.
Can anyone correct me on this?
Also, would this affect piped and invidious too?
