> The loss of an independent Slack is sad, because Slack’s strategy wasn’t just a standard attempt to gain market power. As a company, Slack’s team thought carefully about product design, and that care showed.
That's not an economic argument, it's an aesthetic one.
The fact is, it's natural in many industries to coalesce around 2-3 major competitors. And as we can see, that's exactly what's happening here. Slack isn't being snuffed out. It's living on as part of one of the ~3 major players in the space, which is a natural and desirable outcome for consumers who want simple bundled all-in-one solutions.
And Microsoft hasn't been "losing money" by including chat functionality in Office -- what you're describing is predatory pricing which is simply not the case here. Office is an expensive product that companies pay tons of $$$ for.
