I agree. Two other points: 1) While more sites might be targeting Chrome now, the browsers and standards are generally more inter-operable now than they were in IE6 days. jQuery came from a time where each browser supported drastically different APIs. These days Chrome and Firefox generally support 80-90% of the same APIs, with generally only a few cutting edge features and edge cases differeing. 2) Microsoft adopting Chromium as its core is in direct contrast to IE6 days. There are now two big players building on Chromium instead of one. That could have never happened with proprietary IE6. Now there are two hands on the wheel of Chromium, so to speak. And if Google won't play ball with Microsoft, like you said, Microsoft can fork Chromium, but I imagine both Google and Microsoft want to avoid that if possible.
