On side note on this topic, I am pretty sure I am being A/B tested on youtube with some form of dynamic ad inclusion. A friend sent me a youtube link, I opened it on Firefox for Android (with the latest ublock lists), it immediately served me an ad. This had never happened to me before, I actually assumed I opened it by mistake on Android's youtube app. The only way I found that I could block it was using the older embedded videos url (www.youtube.com/embed/<video-id>) Anyone has more info on what are they doing exactly? I found a reddit post with similar complaints but everyone was equally clueless. Seems like they decided to point artillery at ublock.
