Teams BundlingNarrow moat
Microsoft (MSFT) — moat facet
The remedy arrived and the margin it was meant to compress went up: 59.9% against 53.2% three years ago, with Teams still inside the suite.
The bundling of Teams into the Microsoft 365 subscription was a characteristically Microsoft maneuver1, and a revealing one. Rather than charge separately for workplace chat and collaboration, Microsoft folded the capability into a package companies were already buying, so that the marginal cost to the customer of adopting it was effectively zero. When a good-enough product is free inside something you already pay for, the specialist charging for the same thing on its own suddenly has a very hard row to hoe.
The tactic worked with brutal efficiency. Teams went from nowhere to ubiquity in a few years, not because it was clearly the best collaboration tool — the specialist rival was, by many accounts, the better product — but because it was already there, already paid for, and already integrated with the email, the calendar, and the documents. Distribution beat quality, as it so often does when the distribution is free and enormous.
This is the same lesson Microsoft has taught the market across its history: a good-enough feature, bundled into a dominant product at no extra charge, can flatten a better-funded specialist. The bundle is a weapon, and Microsoft wields it with a practiced hand, using the grip in one market to win the next.
For the owner, Teams bundling shows the franchise's grip working as an engine of expansion, not merely defense: each new capability folded into the subscription both justifies the price and colonizes a new market at almost no cost — the installed base turned, once again, into a launchpad. It is the flywheel that has driven Microsoft's expansion for forty years.
Narrowing — the one clearly eroding piece of the Office grip. Bundling Teams into Microsoft 365 was a potent weapon that helped it crush Slack, but regulators called it anticompetitive: after EU pressure Microsoft agreed to unbundle Teams and sell it separately, worldwide. That removes the free-with-Office advantage that drove much of Teams' rise and gives rivals room to compete on merits. Teams remains huge and deeply embedded, so this is erosion, not collapse — but the bundling lever specifically is being pulled out of Microsoft's hands.
Bundling shows up as margin, not as revenue: the segment that carries Office, Teams, LinkedIn and Dynamics now keeps sixty cents of every dollar, nearly seven points more than three years ago, and it does so while giving Teams away inside the suite. European unbundling is the thing that could reverse it; watch this line, not the remedy.
