> The European Commission has been investigating Microsoft's tying of Office and Teams since a 2020 complaint by Salesforce-owned, opens new tab competing workspace messaging app Slack.

For reference, here is the complaint (2020):

In a nutshell:

> The complaint details Microsoft’s illegal and anti-competitive practice of abusing its market dominance to extinguish competition in breach of European Union competition law. Microsoft has illegally tied its Teams product into its market-dominant Office productivity suite, force installing it for millions, blocking its removal, and hiding the true cost to enterprise customers.

So basically, this behavior from MS is the same with IE being bundled in Windows in the 90s and, later, probably Media Player.
