Earlier quoted context omitted.
One could also be a bit more compassionate and just realize that people make mistakes or just don't have every line on their website memorized if they decide one day to just share a YouTube video. I doubt they are actively trying to trick people into letting down their "adblocker" guard so they can retarget them with advertising...
Compassion has nothing to do with taking something seriously. I have compassion for their cause. Read 2 articles and was intrigued. At the same time, spotting such an obvious mistake does make me wonder if their articles have glaring mistakes in them as well.
Someone is aware of the issue of online tracking and tries their best to get rid of all of these things (web fonts, analytics,...) and even states their intent "No tracking". One day they make a small mistake and don't realize that sharing a YouTube link on their website drops a cookie and immediatelly all the good they are trying to do is forgotten.
I hope you never make mistakes.
