The 800-pound gorilla - Johnny Rodgers

Microsoft used their fundamental advantage as an incumbent software leviathan to bypass the terms on which we wanted to fight them. With very few exceptions, they didn’t steal our customers. Our customers loved Slack. But they tapped the massive market they already had and greatly reduced our chance to ever reach them. A company that was already paying a steep premium for the essential tools of Office 365 got Teams “for free” and it seemed fine to them.

That's sounds like 🎩 to me. Winning an antitrust case in the EU in 2024—filed in 2020—seemed to be too little, too late.

Filed in 2020 and resolved in 2024, the suit alleged that Microsoft had used its monopoly power to bundle Teams into the Office suite and give it away for free, thereby undercutting competition and unfairly skewing the market in their favour. In response, Microsoft has agreed to unbundle and charge for Teams.
