While not a part of the community myself and it being hard to judge people's intent, it really does seem artistic subsets of the community genuinely want to support their peers. For context, I follow a bunch of NFT photographers on Twitter (most of them I followed before NFT was a thing) and the community seems really positive. I have absolutely no interest in feeding the environmental disaster that is ETH, but I recognize some people see it as a legitimate way to support creators.
