DM might be a abusing shit but I don’t think you can take away his contributions to techno.
He’s also the only one out of the B3 who could mix worth a damn. KS was not good by any stretch and JA didn’t seem like he even knew what he was doing. I’m sure sync and CDJ have helped with that, but when I saw them on turntables, DM was the only competent one of the bunch.
