They were already scanning every message and DM for data tracking and whatnot to sell anyway, the only difference now is they're using it for TOS violations.

Privacy-wise nothing has changed, but actual consequences for actually bad things like racism / transphobia / csam / etc. is good. The only real issue is what if they decide that sharing a music file is piracy and now your account is penalized? What about uploading an NES ROM to a friend via a DM? Or sharing a link to an anime piracy website?

It's the kind of thing that has to be a balance between making sure users aren't doing stuff that is strictly against Discord's rules, but also about making a good-faith attempt to limit things that can get Discord themselves in trouble from companies who are becoming more and more aware that Discord has been used as a piracy-safe haven for quite some time now. (Like how they're limiting their "using discord upload URLs like your own CDN" issue last month.)
