This seems like another case of using Slack outside it’s appropriate scope.

While you may have impromptu meetings and make decisions on Slack, any company’s most important directives should be codified and accessible outside that medium. You don’t send executive meeting minutes to the whole company and have them parse our what decisions are made: decision-making meetings result in memos and other documentation.

Likewise, if a team’s decision-making process leaves out important stakeholders or makes it difficult to have influence, that’s another management problem that has nothing to do with the use of Slack. You would have the same problems if meetings are held spontaneously at the water cooler, and in fact I’ve seen this very thing happen without Slack’s influence.
