If I get to run a quarry on the Gmail servers, scanning through every personal email to find a subset of say 100 people, the statistic that Google want to publish will state that only a 100 peoples account was violated. In truth however, all customers was violated to create the list of the 100 people which account contents got sent over.
Second, Microsoft or Twitter do gain privilege by cooperate with governments. They become less likely a target for lawsuits directed at violations of competition laws. they also get a easier time lobbying politicians for lower taxes if they at the same time are helping out with spying at the local population.
