"Perfect is the enemy of good" really applies here.
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.
This absolutely does not relate at all to me. I don't make extraordinary claims so I am not bound to provide extraordinary evidence. So your "I hope you never make mistakes" is irrelevant or, even worse, arguing in bad faith.
You can spin it any way you like. Claims should be backed and checked, else credibility flies out the window. I don't get how that's not glaringly obvious.
