Personally, Veritasium is out of that list for me due to some of his more recent videos. He still has some good content but I really disliked that "rods from God" video where it feels like he's basically doing the same thing as the "How Ridiculous" guys and trying to disguise it as science communication. And the (admittedly few) ones where he's basically disguising advertising as his regular content.
Ok so not nessesarialy a dick, just a strong reaction with his name sorry.
In his video saying he has an autistic son, he did a charity event for NEXT for autism, who wish to 'cure' autism, and have worked with Autism speaks before. The actual event before changes made due to criticism had like no autistic voices present. I don't think Mark is a dick because he seems to genuinely love his son, but was just uninformed about the harm that group does.
I'd call that disappointing, Autism Speaks is a shitty group. Neurodivergence doesn't need to be "cured". I even thought Rober might be on the spectrum himself.
Kurzgesagt is a shitty neoliberal who greenwashes the future involving climate change. I'm not sure if he's paid by oil companies or if he just loves huffing their balls that much.
