The opposite could be argued as well: it's design supposed to focus on function alone (after all that was their pitch: put the content front and center, remove aesthetic touches from the "skeuomorphic" UIs, etc.) but with no redeeming aesthetic qualities (which are also important for actual human users).

So, it's not exactly form over function (besides thought into form is necessary for function - you can have a real world lever that is e.g. thin and crooked and it will still function as a lever, but a good lever also has good form -- e.g. be designed to have a good grip).

It's "design ideology and novelty for some manager's sake" over form and function.
