Zulip, or even Mattermost a little bit, offers unlimited hosting for open source communities, and not this "we're going to throw your messages in the trash" stupidity that Slack is doing. It's a grave disservice that Slack is doing to those communities

For privacy, Discord has a bad track record, so as a business, I'd choose Slack over Discord. But I definitely prefer self-hosting communications infrastructure.
in my experience, the mainstream is going for Microsoft Teams, and overwhelmingly so. Any org who has not significantly bought into Slack yet is very unlikely to ever do it, because Teams is now “good enough” and effectively free. Which I guess is why Slack is trying to kill Teams with lawyers rather than features.
Slack has likely jumped the shark.
i’ve been working on a new discord server for people building mailing lists and newsletters and built out an opt-in software channel section where people can opt into #mailchimp, #convertkit, etc. channels without any sort of moderation/admin input needed. it’s a really nifty “self-serve” thing that i’m pretty sure i wouldn’t have been able to pull off with slack.
fully expecting “discord communities-as-product” to be a big thing over the next few years as they’ve built a great platform to do that sort of thing.
