Isn't the whole point of Substack, etc. monetization, one way or another? Maybe I'm just a cranky old man, but that to me goes against 'independent'. But then, I'm not just old enough to remember when blogs weren't monetized, but remembering perusing Factsheet Five to see if there were any interesting new zines to trade with. Maybe you could mark the Substack blogs with a little swastika like an asterisk.
