LTT honestly sounds like a place that just never became professional. Just horrible nerd culture shit that leads to HR and employee problems. They obviously were able to increase production quality, but never developed professional standards and expectations for the employees and content. The content just looked prettier, and they could buy more expensive toys. I sort of question their hiring to. Most of the people don't seem to be knowledgeable about anything, so I have no idea how they got hired.
IMHO LTT represents the PC poser culture which has been growing since perhaps the mid 200x where it's all about show and "entertainment". I don't expect any professionalism (whatever that means is also highly subjective anyway) from LTT but then I don't think that was ever the goal there anyway. For them the product is Linus and the ads. The tests/gimmicks they handle are just vehicles for the show.
