I think it's even more what GN has highlighted: They try to go from entertainment first to hard facts and data. It's very clear that they have not thought this through completely.

Yes, some of their testing solutions are very sophisticated, but there are definitely problems on the management side of things. This seems very much like a structural problem. Communications goes horribly wrong in multiple ways, including errors not being corrected properly. Errors appear very frequently and the employees themselves question the quality of their videos.

Linus himself claimed that he had to improvise a workshop with employees, because they lacked training for what they were supposed to do. Furthermore that he substantially changed things on the fly, because they were garbage from his POV. All of this indicates bad management, but not learning from mistakes and making the exact same ones again proves it.
