Look.
There was one interview where, when asked about DS and JR era DT, KM said he didn't want to respond because he wanted to avoid bullshitting.
But aside from that, I've never seen him bad mouth the band. Why would anyone think he owes them anything?
The only thing KM did that I thought was actually distasteful was leaving before a replacement keyboardist could be found, since the Awake shows were either already scheduled, or the band full-well knew that a tour was coming to promote the album. But that happened over a decade ago, it's in the past.
KM went one way, DT went another. I don't understand why we should give a shit.
