So, if Canon cares about my opinion (and it might very well not),
They don't. They care about the opinion of the market in aggregate, which in general, disagrees with you.
I'd rather not have a camera with more pixels.
Then don't upgrade.
Buy, or don't buy, whatever suits your wants and needs. Whining about it on a forum accomplishes nothing (although we're all guilty of that at some point). If what Canon offers doesn't align with what you want, perhaps there is some other vendor that is more suitable. Expecting/demanding that Canon depress it's offerings to the lowest common denominator is as unreasonable as it is unlikely. Besides, you must surely be aware that nearly every digital camera ever made allows you to capture images at lower than full resolution; so why bother trolling with those same tired old arguments?
