although i feel your questions are kinda trolley and presume quite a bit about the chip scene, i'll tell you what _i_ see from my subjective point of view and hopefully that might offer a bit more of a rounded perspective.
my theory is that many of the older veterans tend to be people who have a cerebral interest in chipmusic as an artform, and they have no time or interest in educating/cultivating/coddling the wave of newer folks who may not be coming in with a similar respect and reverence for the artform. i think what you're seeing is the manifestation of this frustration.
this is not new, btw; this conflict has existed for as long as a few years back when at some point the chip community collectively accepted that if you obtained a DMG and excreted an uncey track out of your bunghole, that meant that you now "know" chiptune and are automatically a chip artist worth listening to.
i personally identify as being in the "chipmusic as an artform" camp and i feel that frustration too. as much as i would like the scene to be as open as possible to newer people, i also feel that the sea of dime-a-dozen snoozer chip tracks undermines the hard work and effort of those who thoughtfully approach the craft and seek to create works that endure the test of time and the critical ear.
cm.org also used to be more of a place for focused discussion on the advancement of chipmusic, and relatively free from the hordes of noobs wanting to know how to make a chip musics, before 8bc went kaput for good. you can understand the disdain when you consider the increased number of dumb questions and topics that have popped up around here lately, by people who don't know any better.
nowadays there seem to be fewer mechanisms for sorting out the gems from the crap. on 8bc, the likes and comments system was a reasonable (though still imperfect) metric that allowed people to easily get a sense of which music was good. i think that netlabels are the primary mechanism for that now, but i don't think that's enough.
there needs to be more trusted curators, more recommendations from trusted artists, and more of a catalogue for finding good chipmusic - otherwise it's harder for the veterans to bother fishing around for stuff by newer artists.
so no, the chip scene isn't dying or anything. but i would say it's in flux, particularly in the area of online spaces. the idea of a "central hub" doesn't really exist right now, i don't know if it will (or should) exist again, but if there ends up being one again that most of the other substituent chip communities can get behind, then chipfolk will find themselves enjoying a new period of stability.
