This "issue" is all being made more complex then it really is. If the best players in the world gravitate to a certain country (conference) then everyone in that conference benefits .... along with the individual athletes. The old adage .... "a rising tide raises all boats" applies here. e.g. .... years ago there was an "issue" of so many European alpine skiers gravitating to NCAA schools (Denver, Utah, etc) .... and taking scholarships away from Americans. It happens in many collegiate sports. However, in the final analysis the skill level generally rises for all participants.
That being said .... I still recall the negativity surrounding Minn/Duluth and all the "foreigners" on their team .... so I understand the resentment at some level .... but at the end of the day welcoming the most skilled players, from anywhere, into any league and doing well by them serves the greater good.
