I would imagine that like any business, it's hard to deal with the fact that if you settle on a particular solution, you'll no doubt have to accept that you'll lose/piss off some people.
As simple as it sounds to just deal with that reality and move on, C-suite people will exhaust every last ounce of effort to find a solution that lets them have their cake and eat it too. (Often on the vague hope that they will be the exception to the rule and blow everyone's socks off)
The great thing about all of that is that it'll probably cost more to try and find the perfect solution than it will just to pick a less than ideal one and move on.
