In a University you work with many people from all over the world, and success depends on doing so. This is the thing I don't quite understand about the position described in the article here. We already do have partnerships with other researchers from all over the world, not just the EU. I've seen some academics talking as if it will suddenly be impossible for colleagues from other EU member states to come and work in our universities, or vice versa. Sometimes they were literally making that argument with a colleague from a US university sitting on one side of them and a colleague from Japan on the other! There are plenty of legitimate concerns that will need to be addressed, and the uncertainty in the near future affecting those planning longer term projects or research funding isn't helpful. However, the idea that it will become dramatically more difficult to collaborate with colleagues from the other EU member states or to run research programmes together seems paranoid at this stage.
