“Microsoft [has] accused Google of manipulating Internet Explorer’s default privacy restrictions in order to ‘bypass user preferences about cookies,’ T.C. Sottek reports for The Verge.
“Google [yesterday] responded with a lengthy rebuttal, arguing that Microsoft’s P3P cookie technology is ‘widely non-operational,’ and that the issue has been around since 2002,” Sottek reports. “The response also points to other offenders, citing a 2010 Carnegie Mellon research paper that says over 11,000 websites don’t use valid P3P policies.”
Sottek reports, “Google’s also specifically bringing Facebook and Amazon into the fracas, citing their similar use of the P3P bypass.”
