How would this be antitrust on the platform's part? How do they gain market share? Someone tried suing Amazon over basically this theory and failed, same lawyer that I'm using in an antitrust case against tp-link for false infringement notices to Amazon. See https://www.courtlistener.com/docket/6169804/mordys-appliance-repair-service-llc-v-amazon-services-llc/ https://www.courtlistener.com/docket/6169804/mordys-applianc... And https://www.courtlistener.com/docket/16562550/thimes-solutions-inc-v-tp-link-usa-corporation/ https://www.courtlistener.com/docket/16562550/thimes-solutio... for my tp-link case, I've mentioned it on HN several times. I have a list of similar cases, some of them use antitrust theories, but it's almost always against the brand/rights owner and not against the platform.
