You can now add Microsoft to the growing list of companies including anti-class action lawsuit language in their terms of service. Following in the footsteps of EA and Sony, the latest Xbox Live terms of service requires that United States users agree to a "class action waiver."
As the language suggests, the waiver bars any user from entering a class action lawsuits against Microsoft, requiring instead that all disputes be solved by "informal negotiation." Should said negotiation fail to solve the dispute, individuals may enter into binding arbitration with the company.
Microsoft certainly isn't the first company to add such language to its terms of service, as mentioned above, and it likely won't be the last. The company has dealt with the looming specter of class action lawsuits before, one as recently as 2010. As with other similar terms of service changes, users may choose to reject it by sending a letter (a paper one) to Microsoft Corporation, ATTN: LCA ARBITRATION, One Microsoft Way, Redmond, WA 98052-6399.
