Isn’t the core of jazz improvisation and breaking the “rules” of music? If that’s what they’re doing, why would we disqualify it as jazz? A lot of folks had this opinion of Miles Davis doing jazz fusion in the 70s on Bitches Brew and Live/Evil with his squeaky, borderline abusive trumpeting, or of Herbie Hancock doing weird space synth stuff on Sextant and funk fusion on Headhunters. I don’t see how what you’re saying isn’t just gatekeeping that’s not really in the spirit of jazz.
