Microsoft facing UK antitrust lawsuit from Slack over Teams 'bundling'
Overview of the Antitrust Lawsuit and Related Developments
Slack and Salesforce File Lawsuit Against Microsoft
LONDON, April 27 (Reuters) - Salesforce and its workspace messaging app Slack are suing Microsoft at London's High Court over alleged anticompetitive practices relating to its Teams app.
Slack Technologies LLC and related companies filed the lawsuit on April 23, which a Slack spokesperson said was "because Microsoft's practices harmed competition, using tying and bundling of Teams to limit customer choice".
Microsoft's Response to the Allegations
A Microsoft spokesperson said the case lacks merit.
"Slack's lackluster growth, compared to Zoom and Teams, was based on inferior capabilities when COVID-19 hit in 2020, and had nothing to do with Microsoft," the spokesperson added.
Background: Previous Complaints and Regulatory Actions
Slack had in 2020 complained to the European Commission, accusing Microsoft of bundling Teams with its Office product to gain an unfair advantage over rivals.
European Commission's Investigation and Outcome
The U.S. software giant avoided a potentially hefty fine by promising reduced prices for Office products excluding Teams in an agreement with the European Commission last year.
