When buying a new software larger companies need to think about

1. Costing

2. Who will manage it and how integrated is it with everything that exists

3. How much manual effort and time is needed to set it up and maintain it?

4. Who will provide long-term support? Will the company be around in five years for sure?

5. Who else is using it?

6. Does it work on all platforms?

Quality is not a quantified criteria and it is because of these questions raised that a lot of bigger enterprises end of with Teams.

From what I have seen, the decision to use Slack is made bottom-up, which is not how most orgs work.

Lastly, most companies in the world are not massive to have scaling issues. Even in those that are massive, most of the teams work in silos.
