Contrary to popular conception, GPLv3, at large, dramatically reduces risk for commercial use compared to GPLv2 -- https://ftp.heanet.ie/mirrors/fosdem-video/2015/devroom-lega...

But as long as companies like Apple whine about it (and sometimes outright lie about it), people will continue to believe that it poses a great risk to commercial use.

Edit: Not Google. Google has been fine on GPLv3 for years. It's individual Google employees that have said incorrect things about it, but I can't find a reference for what I'm remembering.
