I fully agree. Adds which are integrated into the content, especially into the youtube videos are difficult to impossible to block, but also usually acceptable because the content provider or the youtuber do stake their reputation on them and have full control about the content. And my experience matches yours, I am much more likely to get actual interesting information and consequential the ad might lead to an actual purchase, if it is not generated by tracking me - usually those ads just repeat what I looked at recentlxy - but by being related to the content I am interested in. Much more likely to be something interesting and especially new to me.
