UX and UI specialists is how you get the crap that is foisted on us today.
Famous example when you unleash them on a project: Windows 8.
I will admit it is a knee jerk reaction, and it seems like maybe we are turning a corner to refinement over mass changes.
One of the major issues with paid software and UX and UI designers is that in order to keep a job, they keep making changes. And nothing is worse than making changes to customary patterns.
Perhaps FOSS wouldnt have that problem, as the job is labor of love. Who knows.
