Revolt is an amazing project and has a lot of great energy behind it, but one must not forget the issue that is scale. Discord is absolutely humongous, serving millions of concurrent users with pretty good performance overall. I'd love to see Revolt reach such userbase, but realistically, two 2nd year CS students are unlikely to get there. For a platform to reach such volume there needs to be money, which is likely to come with strings attached. Though what you say is true -- Revolt has strong open-source roots while Discord has always been a VC fueled company, so I'll keep my hopes hehe

Regarding Nitro, I agree it is a bit too much, but I actually think a subscription of sorts with bigger upload limits, streaming quality and so on (the original point of Nitro) is a pretty nice model to sustain a platform since it helps cover the cost of all needed infrastructure. Of course, Discord Nitro has since gained a lot of extra fluff and nothing impedes Discord from both selling a subscription and our data (which they're likely to do), but the premise is quite reasonable.
