For those who skimmed TFA:
Last month, Google changed its policy stating that "advertisers will be allowed to use trademark terms in their ad text even if they do not own that trademark or have explicit approval from the trademark owner to use it," Rosetta Stone said
The problem is NOT Google infringing upon the trademarks that Rosetta Stone holds. The issue is that Google is now willingly allowing Joe Schmuck, a competitor, to use trademarks to their own benefit. This seems like a pretty obvious infringement issue. I'm confused though, as to why Google JUST now started to allow this. If it was a no-brainer back when Adwords started, wouldn't they have allowed it at that point? Sounds to me like Adwords revenue was down, and allowing the use of non-approved trademarks in ads made the Adsword space that much more appealing in hopes of getting people off the fence when evaluating their advertising budget.
