So, all that in-line javascript on my website suddenly is "proprietary" even though it's usually just a few lines? (as a consequence, my entire site won't work for users with this enabled)
Please contact your local politician and make the copyright scope more sane. That way, a few lines won't be copyright-able and we don't need licenses for it.
I mean -- the websites you are visiting are bound to be using non-free proprietary software. At least a few of them.
Actually -- the routers your packets travel through are using proprietary non-free software!
The BIOS that boots your PC is non-free and proprietary!
Just throw your computer out -- that is the only sure way to stop using non-free software. (actually, don't throw it out -- just mail it to me ;)
