7 billion people use Google. If you look at the likeliness of it happening to one guy out of 7 billion, it would be very, very small. But the problem is, once it is banned, you will probably lose a lot of important stuff permanently.
It’s probably closer to 70M but that’s probably absurdly off too. I bet there’s 70M people in the US alone who use Google services for valuable information. GMail alone is massive.
