Couldn't you say the same even for native mobile gaming? Or even PCs vs. consoles...
There are plenty of game types -- some "casual", some not -- that are perfectly satisfied by either lower hardware or arcane/wasteful software stacks. And you can benefit from the ease of development, distribution and cross-platform capabilities. Energy, sure, but with browser-based 2D games that's mostly CPU, so given the identical native game we're talking about what, a 30W difference? Might as well tell people not to play triple-A games with their SLI GPUs...
This isn't really a new discussion, as you can bring the same argument for desktop apps, too. Look at something like extjs, compared to native GUIs. Wastes heckuva lot of resources to try to look like a real application and will never reach that (like early Java...). But it's darn convenient...
