Well, I think of that more being due to their mismanagement with the whole WMR ecosystem. "Sterile corporate VR meeting rooms" sounds like exactly something that would have been from Microsoft rather than Facebook, but they tried too hard in some aspects (a half dozen companies making nearly-identical-but-not-really headsets! support built into the OS so deep that to remove it they had to brick everyone's headsets!) and not at all in others.
