According to the foreign media onmsft, more than a year ago, the number of users of Microsoft teams reached 180 million. When asked about the milestone, slack’s chief executive, Stewart Butterfield, said the platform posed no threat to competing platforms. A year later, Butterfield is using Twitter to defend slack’s new antitrust lawsuit against Microsoft in the European Union, claiming that the company is crushing competition.

in a lengthy and sometimes puzzling “storm” of twitter, Butterfield tried to clarify slack’s new antitrust lawsuit against Microsoft and the existence of companies that he thought made it worse.

according to the public statement of the lawsuit, slack believes that Microsoft’s binding of its corporate chat function with its dominant productivity suite constitutes its anti competitive behavior.

the crux of Butterfield’s online abuse seems to be that people who are already using Microsoft office productivity suite don’t have a chance to try slack and then choose slack instead of teams. Butterfield and other slack executives want the EU to force Microsoft to remove slack from office, making it a stand-alone product and charging it a “fair price.”.

although slack’s argument seems to echo Microsoft’s antitrust lawsuit in 2000, it seems that the company may rely more on nostalgia than on actual cases.

slack is seeking to investigate the “responsibility” of Microsoft. In the European Union, it can be said that the threshold at the consumer level is lower than the definition of anti competitive behavior in the United States. For slack, the potential problem in the future is that in the anti-monopoly investigation of Microsoft in the 1990s, the company was not identified as “bundling”, but was identified as other illegal means, and its enterprise chat competition was not so obvious.

in addition, Butterfield and slack are aiming their crosshairs at Microsoft, but may be blind spot to a more direct threat in Google’s latest bundling efforts, which will pose greater risks to the long-term development of slack.
