Slack saw the risks of being a "simple, elegant collaboration darling, and tried to pivot into operations and workflows over the past 3 years. I haven't looked into the feature set much, but I think most customers rejected the idea because it seemed robust and "un-Slack-y".

I always thought the lack of adoption in this feature set was a marketing failure of Slack, but I'm now seeing it as bait for a Salesforce integration.
