The change to a proprietary license can be about reducing risk, particularly in competition that forks/reuses the open source to offer competing products. It's reductive to just ask "number go up?" and conclude all these companies made stupid choices. It would make more sense to look at the licenses case-by-case and get some idea of what each company was trying to protect. I doubt that any of them switched over to a proprietary license for branding reasons.
