I don’t know what “morally lazy” means as the author never defines the construct. Discord has an uncertain monetization model, sure. It’s not great for privacy. It will, no doubt, follow Doctorow’s “enshittification” model.

And then I’ll just spin up a Mumble server or something. So what? Should I feel bad for using a service while I can? Should I feel bad for having fun conversations with my friends? Maybe not everything has to be a fraught struggle of good vs evil.
