Making everything illegible is necessary, so they can sell you a legible design as the next big revolution. Just not in one step. The return to legibility will be a multi part story with cliffhangers, betrayals and everything else it takes to keep you hooked and Apple in the news.

There is no designer in the world making bad designs as part of some conspiracy to enable their employer to launch improved designs several years later. There’s no company that operates that way.
