Doesn't age well and leaves a lot of bad message even with all that yapping of walls of text. Here's some examples:
It's like they believe in fixed talent which isn't the case. They unironically believe the older you get that the less likely you become successful when it isn't the case. The older you get the better polished your skills are, they even underestimate manga assistant too much.
They're a bunch of grifters, they don't seem to have passion on their work. It's obvious when they make a gag manga. They just wanna "win".
They also think plot ideas is what wins a manga, it isn't. It's the execution. Best example of this is vagabond and slam dunk. These plot is pretty simple, a samurai and just basketball but it's one of the best manga out there.
They seem to have huge hatred on other magazines, kirara. They have a huge hatred on moe characters for no reason and depict anyone liking them as old fat losers. While they themselves are immature enough to enjoy pantyshots.
They're not even good mangaka, too much walls of text. No memorable panels, chapters. That's why these series is so forgetable. That's why I never bothered reading death note too much walls of text, only enjoyed the anime.
