This guy was in many UN meetings in relation to the compact. If you watch the interview, his view is that Europe has colonized many places, so it only makes sense that Europe now open its borders. He specifically states in the interview he has no concern for nationalists or those who worry about mass migration. He says that they need to drive the fear of mass migration out of the people of Europe through public education programs. He says that it's a matter of people's viewpoints needing to change. He's very much pro-immigration. The view that mass migration into Europe is inevitable, and that the UN and its surrounding organisations need to facilitate that and make it "safe, orderly and regular", is widespread among the people writing and setting up these documents and allocating the money the UN and it's partner organisations spend. That's why I said, Europeans are funding the welfare behind the facilitation of mass migration into their countries. If you want to find out more, consider documents like these and their supporting studies. It is also largely filled with ideological babble, which is why I am less than optimistic about mass immigration and the supposed integrated Utopia that is supposed to arise from that:

We've seen how well integration works in Britain and Sweden...
The part about how Europe colonized many places was just a description of how Europe itself was fairly insulated from the rest of the world for a long time, which can make it hard to suddenly start accepting a lot of people from elsewhere because it's a big change. There was nothing at all about this meaning Europe should open its borders.
Can you provide a link/source for these groups?
The "Open" in "Open Society Foundation" also has nothing to do with "Open Borders". A open society is defined by freedom of speech, equality before the law, high social mobility, more interested in trying new ideas than in defending the status quo, etc.
It's the same ideology that made him spend his first billion on fighting the communists in the 1980.
