The European Union has ruled that Microsoft breached antitrust rules by bundling its Teams communication platform with its Office software suite. This decision may require Microsoft to unbundle Teams from Office, potentially affecting the market for chat and video conferencing tools. The ruling is part of the EU's efforts to promote competition in the tech industry. Microsoft's bundling of Teams with Office has been seen as a competitive advantage over other chat and video conferencing platforms, such as Slack and Zoom.
