All the Sony DSLRs and recently the GH3 has a tilt screen. Those cameras, while being excellent for stills, realize the video market exists and is growing and cater to them as well. Canon has made no changes to their video features in the past three years. I'd say that is Canon being ignorant as usual. If Canon introduces another camera with a tilt screen, I'll be the one laughing. If they don't, Canon is continues to be ignorant.
And so what if Sony has it? It doesn't mean Canon should have it. Not now at least, 'cause I haven't heard any Canon users migrating to Sony because of this feature. Canon being ignorant? Of course not. Do you really think you know something Canon doesn't? They won't give it to you because you wouldn't switch anyway. And when the time comes that Canon introduces another camera with a tilt screen, they'll be the one laughing - not you - because you'll be buying that camera.
It's just silly how a lot of people here just look at the small picture and say something in the likes of "I want a 7D2 with 1Dx + C300 features for ~$2k". C'mon, Canon is selling a million different cameras and each one needs to have its own feature set and not cannibalize sales from each other.
You want a body with all the bells and whistles? There's one out there, but you probably can't afford it. Otherwise you wouldn't be complaining here. Or you would've switched already.
Fact is, most people complaining here about Canon wouldn't switch anyway, because there's no better alternative. And Canon knows that. They won't give you all the features you want, but just the ones enough to make you spend more money upgrading and stop you from switching.
Canon ignorant? It's the opposite actually. It's why they keep making money.
