… one would think that a professional would know about various problems with various licenses under linux (why x can do what y cannot do). my personal opinion, independent of intel/cl/devs and your codec problem with ff: this edx-site is also completely unacceptable in other areas, and an example that the web is beyond repair (my early days: html/css only, except the js-zombie & of course no tracker & co. at all). sometimes i wish gödel was right.
