While the decision can be made by one person, I'm not sure this is true. There is a big switching cost for most team tools.

* There's going to be a lot of discussion and consensus building. Most of the team is going to have an opinion on the subject.

* Setting up new accounts for team members, teaching team members how to use the new tool, and change management all take time.

* Most teams have integrations within their chat apps, these will have to be switched or re-implemented to use new APIs.

I think it's fair to say that most team tools have good moats. The longer the team has used a tool the stronger the moat becomes.
