The Gnu Free Documentation Licence (GFDL) has not been embraced with nearly as much love as the GPL and numerous issues have been raised:
*Non compability with GPL (both ways).
*Non-freeness (as deemed by Debian) of invariant sections.
*Cumersomeness of having to print the full licence when distributing physical printouts.
Wikipedia for example does not accept contributions licenced under the GFDL only.
What do you see as a way forward in adressing the issues raised regarding the GFDL?
Look at Sweden for example. What you're stating simply isn't true. In 2013, 15.9% of the population was born outside of Sweden.
Anyone in the EU is free to settle in any other EU contry (Sweden is a EU country, just as Romania).
Anyone from outside the EU is free to work in Sweden provided that they can show an offer of employment with a monthly salary of at least 13000 sek
(about 1560 usd), and after four years they can apply for permanent residency.
The diffrence is a welfare state and unions.
