Well what I mean is, imagine if Ubuntu at some point started to be opinionated about what a Desktop Linux should look like more and more, with some people inside fully responsible to build the UX in every detail, how binary packages should be trivial to download and install, how drivers should be trivial to install (for a subset of the hardware that is fully supported at least), and so forth. A distribution that tried to provide a full experience, instead of being, indeed, a Software Distribution. In that case you can have people in charge of deciding all the details. Payed people to do the best work possible.
