[WH40K] If Imperium discovers modern-day Earth, what happens to us?

Would we be allowed to keep Internet? Would a planetary government be established? Would all our science be forbidden as heresy? What about religions? What would be the tithe?

UPD: I was mostly asking in terms of how do they change our religions/technology/politics. Let's consider the variant where WH setting does not exist in our culture.

We're fucked. All the mentions of the Chaos Gods in print and on our internet means they will just Exterminatus our entire planet after a couple days of looking around. Add to that our thirst for knowledge and drive to increase our technology level, as well as our lack of reverence for the Emperor and machines adds wood to our fire.
