If it's not the questionable qualifications(although he is an enthusiast, he has a limited professional background in electronics repair and software development, two things that are constantly featured on his channel), it may be because of his gun-toting libertarian leanings - some years ago he accidentally posted a video where he was proudly open-carrying on a shopping trip. Of course some people voiced outrage. I think the guy is good at making videos - but it's with an asterisk. He doesn't have a lot of expertise to share, but he wants to be seen in control. So the videos themselves are always really polished, but then the thing he does is something he should have asked for help with.
