The European Commission used its statement to detail its concern "that Microsoft may have granted Teams a distribution advantage by not giving customers the choice whether or not to acquire access to Teams when they subscribe to their SaaS productivity applications. This advantage may have been further exacerbated by interoperability limitations between Teams' competitors and Microsoft's offerings. The conduct may have prevented Teams' rivals from competing, and in turn innovating, to the detriment of customers in the European Economic Area."
