In a response to the its call for comment on behavioral targeting guidelines, Microsoft admonished the Federal Trade Commission to look beyond behavioral advertising and examine regulations on all forms of data collection, such as for contextual advertising.

That would appear to be a broad swipe at Google and Yahoo, Microsoft's two competitors in online advertising.

The comments are incongruous with just about everyone else's response to the FTC's call for comment on behavioral targeting practices. Most everyone else outside of privacy advocacy groups called for less broad language in the proposed guidelines.

Microsoft's responses specify the FTC implement a tiered structure for online advertising, with different privacy disclosures required at different levels.
