The last thing I want to do with complete strangers is give them my phone number lol. Aside from obvious privacy concerns and call quality concerns, Discord is internet-based, so I don’t need cell service or international calling to talk to people.

Screen sharing during voice calls is super helpful as well. It’s a pretty major feature of Discord, Teams, and I believe Skype (RIP), but Teams is not really any better than Discord and a lot more bloated.
