The article doesn't really seem to make any moral argument (probably because it's unfinished - maybe don't post it until it is?). Yeah, Discord is financially unsustainable, but that's just because it's still in phase one of the enshittification cycle. At this stage, venture capitalists are basically subsidizing the service for everyone. Maybe I'm just myopic, but I don't really see anything morally wrong with enjoying a service paid for by a greedy billionaire. And once the enshittification ramps up, well, there are always alternatives.
