Yeah, those type of vids can be annoying.
But I wouldn't call him a low IQ user. He looks more intelligent, than the usual, average annoying clickbait music producing youtuber, that are all over youtube, who try to be critical to look cool to their livestreaming audience and viewers. But at least he tried to understand lmms, despite his struggle to learn it a a short period of time. But yeah, I can understand why any lmms user, would be turned off of that vid. Especially when he compares it, to paid Daws like Gps said above.
Don't take them on guys. Some of them, do that with Synth 1 too. They would compare Synth 1 to Sylenth and other fancy vst plugins, and try their best to make Synth 1 look very bad, and get hate in the comments section. In one case a few years ago, a youtube producer who made a comparison vid, was actually sponsored, to make a fancy vst look good and make Synth 1 look like crap. Then it got more interesting. He even admitted to one annoyed commenter, that yeah, it was a clickbait sponsored vid, to promote a fancy paid plugin. Now what do you think of that? It makes you wonder sometimes. Lol!
