By removing slack this adds a ton of work as all the integrations and workflows that have been built into slack over the years need to be rebuilt. All to save 0.2% of the cost of a person Now in our specific company the latest hotness only lasts about 2 years, from messanger to lync to skype to zoom to teams. Each is massively disruptive and comes as a major project for a team of project managers. (They are also trying to downgrade us to office 365, which for our purposes removes archived emails more than 3 years old) Now for a beancounter it may seem that spending £6k a month on someone, then pissing them off by making a £10 a month saving, it worthwhile. That's because the beancounter doesn't factor in the cost of pissing people off.
