Wrong on all accounts, it’s completely unrelated to the DMA.
The Commission is concerned that, since at least April 2019, Microsoft has been
tying Teams with its core SaaS productivity applications
The conduct may have prevented
Teams'rivals from competing, and in turn innovating, to the detriment of customers in the European Economic Area.
If confirmed, these practices would infringe Article 102 of the Treaty on the Functioning of the European Union (‘TFEU'), which prohibits the abuse of a dominant market position.
On 14 July 2020, Slack Technologies, Inc. submitted a complaint against Microsoft, alleging that Microsoft illegally tied Teams to its dominant productivity suites.
Article 102 TFEU prohibits the abuse of a dominant position that may affect trade within the EU and prevent or restrict competition. The implementation of this provision is defined in the Antitrust Regulation (
Council Regulation No 1/2003), which can also be applied by the national competition authorities.
Article 11(6) of the Antitrust Regulationprovides that the opening of proceedings by the Commission relieves the competition authorities of the Member States of their competence to apply EU competition rules to the practices concerned.
Here you can read up on it.
The European Commission has informed Microsoft of its preliminary view that Microsoft has breached EU antitrust rules by tying its communication and collaboration product Teams to its popular productivity applications included in its suites for businesses Office 365 and Microsoft 365.
