They do it to Opera as well. Pretty much trying to bully out anyone they can in browsers. I get annoyed at their excessive "try Chrome" popups on websites as well. I don't care what browser anyone uses, but trying to push one's browser as the "one and only true faith" on every major service they provide is annoying.
With everything having full acid compliance and keeping up with modern day features, there's very few reasons not to support the most current browsers out there, especially when you're a company as large as google. Granted this site is using things like filesystem API[1] that only Webkit has so far I believe so it kind of comes down to "showing off the bleeding edge" in this case.
