There are lots of different plays, but the most obvious version is, Microsoft salesdroid will ask if you're using Slack and come back with, "tell you what, Teams will cost you nothing, we'll zero that." Now $manager can either pay for Slack too, or replace it for "zero cost".
That discount probably goes away next sales cycle, but in a 20k person company, saving that $5/head/month (or whatever it is) means someone hits their bonus target this year.
Tada!
