Big tech companies have used tying to maintain and extend their dominance. Short thread on this unfair practice and the still good law on it.
Tying is when a firm conditions the purchase of one product on the purchase of a second, separate product (through contract or technical integration). A familiar example is cable bundles: To get the channels you want, you must also pay for the channels you won't watch.
Through tying, a dominant firm can exclude rivals, coerce consumers, and extend its power into new markets. Here are three examples from the tech sector.
In their suit against Google, @JusticeATR and eleven states accused Google of tying its search and other apps to the essential Google Play in their agreements with mobile handset makers https://www.justice.gov/atr/case-document/file/1329131/download
The House Antitrust Subcommittee report documented how Amazon ties the coveted "Buy Box" for sellers with their use of Amazon shipping and delivery https://judiciary.house.gov/uploadedfiles/competition_in_digital_markets.pdf
Over the summer, Slack accused Microsoft of bundling Teams with its dominant Office package as a means of foreclosing Slack and other competitors in collaboration software https://www.nytimes.com/2020/07/22/technology/slack-microsoft-antitrust.html
The law remains good: tying by firms with "appreciable economic power" in a market is illegal. @openmarkets summarized the harms from tying and the law in an amicus brief filed in the Third Circuit on Tue. Many thanks to our local counsel @jasonrathod! https://static1.squarespace.com/static/5e449c8c3ef68d752f3e70dc/t/5fa2e95d69b4a72ccd79c842/1604512094415/OMI+Brief+in+Ellison+v.+ABOS+-+Filed.pdf
Will @JusticeATR, @FTC, and state attorneys general build on the Google case and enforce anti-tying law against Amazon, Microsoft, and other monopolists?
