It's also what I, as a user, want. I don't want some middle-man corporate "platform" (of which there are very few to actually select from to suit your personal tastes) inserting their vision of what UIs should look like into interactions between me and the service I'm connecting to. I want my platform to be as invisible as possible and interchangeable with other platforms. The more things stay the same when switching between platforms, the better.
