I came here to say this.
I'm quite the fan of Qt, but it's far from an industry standard. HTML5 + wrapper probably has as much, if not more, adoption.
And, once you use iOS or Android to dev GUI, some modern, convenient, and well-crafted patterns begin to emerge. They're not perfect, but they're nice to use. Honestly, if Google wants to use their own toolkit and publish it as open source, why should anyone complain about that? Some very interesting ideas may come out of it and be brought into other projects. Just as Mozilla's XUL was clearly aped for Microsoft's XAML, open source contributes to the field as a whole, not just one particular project. There's no need to lick the pizza with open source.
Only the ever-trolling slashdot community could turn Google releasing and dog-fooding an open source project into a bad thing.
