Canon 6D: Why is the interface so badly broken?

Background - I got my first dSLR in September 2004, the Canon 20D. I then upgraded to the Canon 40D. I have a couple of L series lenses, a 580EX, 430EX, battery grip, timer remote, etc., so I'm reasonably invested in the EOS system.

I am 6 days away from picking up a Canon 6D, however I am having real difficulties getting past the fact that from a user interface perspective, it is a broken camera.

Firstly, I use Flash Exposure Compensation quite a bit, so I'm trying to convince myself that when doing a shoot with the 6D, leaving the Quick menu on FEC would make it quick to get in and make a change. (The quick menu will stay on FEC, even if I change stuff like ISO with the direct buttons, right?) The trouble is, after having a FEC button on my Canon body since 2004, why am I now forced to be messing around in the Quick menu? How is the "Quick" menu quicker than having the ISO/FEC button? Clearly Canon want's to punish customers who can't afford the 5D Mark III. If putting FEC in the Quick menu was about improving usability, then all new Canon bodies would have single mode buttons, but this is clearly not the case.

A better example of this broken interface is the "Zoom" button. Really Canon? Why do we loose the joystick to have a zoom button? If I've hit the "Play" button, what was wrong with the method of using the two upper-right buttons for zooming in and out? More precisely, if I'm in "Play" mode, isn't it logical to think that I will likely want to zoom in to the preview? Why do I have to hit another button to tell the camera that I now want to zoom? This is a design decision that should get someone fired. The answer clearly is that the 10D-60D/7D/5D/1D zoom method was too convenient, and customers who can't afford the more expensive full frame body again need to be punished with more superfluous button pushes.

I should point out that I am familiar with the 60D and it's "simplified" interface, and you'll notice I didn't buy one. At least the 60D doesn't have a stupid Zoom button.

After reading some 6D reviews I understand that the 6D is aimed at "the social" customer. Really? Seriously? A $2,100 dollar full-frame body is being aimed at the social media crowd, because they are really clamoring for one? Now clearly, in Canon's mind, these "social media" customers cannot cope with camera buttons that do more than one thing - lest we all forget that "social media" users with their smart phones are accustomed to their touchscreen virtual keyboards having each "button" doing about 5 things. (The 6D front dial seems to be used for about a million things, but let's not confuse things. In Canon's mind, we obviously all use our mouse scroll wheels far more frequently than left-clicking.)

Clearly I'm of the opinion regarding the 6D that a) most significantly, as a long time Canon customer my familiarity with the exiting interface has been disregarding as a significant design consideration; b) Canon believes that "social media" customers who are very accustomed to having a single button for 7,P,p,Q,q,R,r,S,s cannot deal with an interface where ISO and FEC, etc. can share a button; and that c) if you want a full frame Canon body with a non-broken interface, you need to pony up another $1,200 - $1,400 for the privilege. One can get some nice glass for $1,200 - $1,400.

Now I anticipate the response to my concerns may take the tack of "You can't expect 5D Mark III features at the 6D price." Unfortunately, I don't believe that this is a reasonable consideration in this context of the user interface. With the difference in autofocus system, no dual slot, no RAW HDR/multi-exposure, no uncompressed HDMI out, etc., there's a reasonably amount to differentiate the 5D Mark III and 6D, without having to break the user interface on the 6D.

What's really unfortunate is that if I vote with my wallet and do not buy the 6D, due to it's broken interface, Canon would probably interpret this as the 6D Mark II should get rid of more buttons in favor of a touchscreen

I cannot afford the 5D Mark III but can really benefit from the image capturing capabilities of the 6D. I'm really angry with Canon right now that for my $2,000 purchase, Canon gets to punish me with a broken interface. (With the price reduction of the 5D Mark II it's been REALLY tempting, but outside of the user interface not being broken, a Mark II doesn't make sense.)

It would be great to be able to contact someone at Canon to voice these concerns, but considering how long it took them to figure out that opening the card slot door didn't mean you wanted to throw away anything in the camera buffer and that mirror lockup is a feature best buried in menus, I don't think they care about my opinion as a customer anyway.

Thanks for reading my rant. Any feedback on the day-to-day usability of the 6D would be appreciated.
