What's wrong with having more sovereignty over your data and infrastructure? You don't need to stop working on the mentioned issues together but cutting foreign spies the access to your citizens data and reducing their leverage.

That's life, spies going to spy, state psychopaths from the military and the three-latter agencies exist regardless whether you see them or not and they don't care about the "common good". They must be taken into the account.

The less power humans have over each other - the better. Instead of pressuring each other to bring profits people would be able to speak like equals.
