I don't understand any of this. Microsoft develops and publishes 'protocols' (used lightly) and everyone hates them because they are pushing workable code out on everyone else... Bunch of people in a committee take three years trying to build the security token system to end all security token systems and have yet anything to show for it and we are sad? Why are people trying to do this anyway? oAuth is just an idea.…
"workable code" is a tangent and really has nothing to do with the reason we avoid Microsoft protocols. More to the point we want to avoid APIs with elements that facilitate vendor-specific implementations i.e., lock-in. Like MS' OOXML, Oauth 2.0 has special interest written all over it.
