since a lot of folks are becoming newly interested in escaping corporate silos and moving to community-based services, are you aware of @matrix?
Matrix is to Slack and Discord, what Mastodon is to Twitter: a decentralized, federated network based on open standards/specs. It also supports full end-to-end encryption, just like Signal, so you can exchange messages privately!
If you find the fediverse interesting/inspiring, I recommend giving matrix a whirl. The quickest way to get started is to head over to https://app.element.io/ and make a (free!) account (although you can also join any number of other home servers, or host your own--they all talk to each other!).
If you _do_ end up checking it out, please do say hi! I'm @zkat:zkat.tech over there. I also manage a "space" (a group of channels, kinda like a Discord server) that you can join by clicking here: https://matrix.to/#/!tKdDSgQTxQzcOuTXqV:matrix.org?via=zkat.tech&via=matrix.org&via=envs.net
I hope this sparks your interest! I'd love to see you over there, too!
The social network of the future: No ads, no corporate surveillance, ethical design, and decentralization! Own your data with Mastodon!
@Ashx Element is probably the best mobile app out there rn, imo
