I actually don’t know if/how the ad block people worked around it or if YouTube pulled back. The problem with DAI on podcast and in stream ads is that the ads aren’t always 1:05~1:35, the ad could be longer or shorter, then the next ad won’t necessarily start at the same time, and most definitely won’t end at the same time. So sponsor block won’t know precisely where the ads are, thereby making it much harder for a crowd sourced solution to accurately skip embedded ads. Hopefully they figured out a way, but as mentioned earlier, I don’t know what happened to that experiment.

[With hindsight] The commercial use of the internet should never have been allowed.
