Personally I think that time has shown noise & industrial culture to be somewhat immune to gentrification and commercialization. Out of all the punk-adjacent subcultures including punk itself that were formed in the late 70s, industrial and later noise culture has been the only to stay consistently DIY and underground, not to mention very anti-commercial. There have been some crossover to more accepted, commercial music scenes but even with Merzbow and some others breaking thru the barrier into larger popular culture awareness, they haven't REALLY pulled the subculture with them. Noise and industrial is still as introverted and obtuse as it ever was. If some people demand more representation for minorities like is common in other cultural movements, no one is in any way obliged to give in. Then again i'm sure there are many active people in the culture who agree with that sentiment, at least to some degree, and will either consciously or subconsciously give minorities (meaning everyone who's not white and male I guess) opportunities to participate. And personally I see that as essential for noise to develop and mutate and stay relevant. Industrial and noise has always been open to all kinds of misfits and weirdos, and I strongly resent any attempt to gatekeep new artists based on their political or cultural opinions or values, even if they clash with the traditions of the culture. Were noise to shrivel into an "edgy boys club" I personally would quickly lose interest.
When there's no real money involved, people can make their own decisions and follow their own values. There's room in noise for everyone and no one is forced to listen or work with people they don't want to.
