Slack makes EU antitrust claim against Microsoft over Teams

Work messaging platform Slack has filed an antitrust claim against Microsoft, claiming the tech giant's rival app Teams has an unfair advantage. Slack argued that it was seeking a "Level playing field" and suggested that, by offering Teams to Office 365 users, Microsoft was making it harder for Slack to sell its own software to the market.
