Claude-in-Slack is a big enough feature to overcome the slack-connect network effect. Openness is absolutely key! I wrote this post because I hoped that if Anthropic is already planning to do this I might be able to influence them to make open-data part of the plan. But openness by itself isn't a big enough feature to get users.

It really sounds like you're asking for something else. More like multiple people to be able to talk to the same instance. Which that's a very different thing than Slack
