How Microsoft Crushes Their Competitors

Slack is actually a terrible example of the phenomenon, because they had a messaging app as part of Office since 2007 with Microsoft Communicator. Slack only existed since 2013.

A much better example IMO is the Power Platform, which might end up being the default no-code/low-code solution for the enterprise simply by dint of being bundled. Though it's not a true bundling either - they charge extra for doing anything more than the basics, which might be enough to get them out of antitrust trouble.
