Michael Sieben is a friendly, talented, hardworking, and generous person. Probably one of the coolest people in all of skateboarding. Anybody who knows him personally or professionally will tell you the same. He is genuinely super down for Austin skating and skateboarding in general. His constant work to keep his brands afloat (or resurrected), not to mention all his work for No Comply, is heroic considering he has successful careers in art illustration and editing all the copy for Thrasher.
You may or may not like his artwork style, but he has been super productive and consistent for decades now and you should respect that. From his illustrations to his zines to concert posters to the old Internet Shack show to art installations, Sieben walks the walk. He may be a 'dork' (he'll be the first to admit it), but that doesn't mean he's a kook. Far from it.
There is probably a thread deep in SLAP about Target stealing his artwork; that wasn't just them doing a similar skull faced drawing and him griping. It was 100% a copy a specific piece of his art
