I wish, but I’m not so sure.
So many (if not most) IT VPs and directors went whole-hog Microsoft suite years (if not decades)ago and are so pickled in inertia that the only thing they “worry”—using that term as loosely as possible—about once a year or less is when renewal comes up, and squeezing a dinner out of their sales rep. They’re on autopilot, because MS anything is the defacto “standard”, and braindead bean counters don’t care about the design/usability of something like Teams, they’re just all-too-happy to take the now “extra” cost of something like Slack out of the yearly budget.
The fact that there are always closed-minded high ranking non-IT people in every company that think Office/365/Outlook is what a computer is (these are the same people that make a word attachment to send you one paragraph of text without styling, instead of just putting that in the body of the email)…means the incentives to evaluate any alternative is even more non-existent.
Microsoft and IT decision makers on autopilot are such strong allies and bosom buddies that I don’t think that Microsoft has anything to worry about in the short-to-medium term, especially the orgs who would be open to to something like Google Apps have probably converted already.
