For me Veritasium lost all his credibility capital by the way he responded to Tom Nicholas’ video about YouTube sponsorships using Veritasium as a case study[1]. In stead of approaching the debate calmly (or better yet, simply ignoring it) he came to the comment section way too defensive, like a lot, basically calling Tom a lair and a bad actor.

Actually that is not quite true, Veritasium lost a bunch of his credibility capital when he made the sponsored content for the self driving cars. I never watched that video as I spotted it was basically and ad and was reluctant to watch his new stuff after that (though I did).
