What? Here is Zulip’s license which is almost identical:
When you upload or otherwise submit content to our Services, you give Kandra Labs (and those we work with) a worldwide license to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes we make so that your content works better with our Services), communicate, publish, perform, display and distribute such content.
The ridiculous pitchforking in this thread is out of control.
That's not in any way a replacement for discord.
