The complaint, filed on January 14, 2025, arose from plaintiff’s allegations that Microsoft Corporation designed its Microsoft Shopping browser extension to steal affiliate commissions owed to online content creators. The complaint alleges that when a shopper clicks on an online content creator’s affiliate link and purchases a product, the online content creator typically gets credit for that referral and earns an affiliate commission. The Microsoft Shopping extension, offered as a free coupon-and-discount search tool on Microsoft’s Edge browser, allegedly usurps this arrangement by surreptitiously removing the online content creator’s affiliate code and replacing it with its own, depriving creators of the rewards for their legitimate marketing efforts.
