This takes me to my next point, while it may not be the greatest example because Jens gets paid to ride whatever components are on his bike, one thing is certain, Jen's would never do this! (disclaimer: this post is not meant as a jab at Shimano)
Even though I don't own a Pinarello or Colnago, it pains me every time I see one of those beautiful frames with any groupo other than Campagnolo. However it is especially painful when it's built with Shimano (Even Di2). If there were indeed gods of cycling, this wouldn't be possible.
Is it too much to ask? Not in my opinion... when was the last time anyone saw a IBM tower with a Mac monitor? Saw a Trek built up with Campy (world's greatest Madone... so wrong), Or ever heard anyone order a Rum and Pepsi? Some things are just never meant to work together.
So who do we have to blame for this? In the case of Team Sky, being that they're a Pro Team and they get paid by their sponsors, they have a good excuse.
The local team, club, and recreational riders are a whole different story. Yes, I know sometimes (a lot of times) they don't know any better. This is the reason it should all fall on the shops that sell Pinarello, Colnago, et al.
As a dealer of the aforementioned brands or (insert favorite Italian frame here), there is a great deal of power, it's a status symbol, it means your store is worthy so just build a kick ass frame with nothing but campy, it's as simple as that. It reminds me of what a man once said: "with great power, there must also come great responsibility".
I must now ask that if you're a consumer, a rep, a shop owner, a shop salesperson or mechanic, do what you can... it's for the good of the sport. And if you're ever in doubt, ask yourself, what would Jens do?
