I think the big problem with Google is their obsessive compulsiveness in collecting data. Searches, chat logs, locations, everything is collected because storage is cheap. The collect it to improve their services, sure, to better target their advertising, of course. And Google may strive to protect that data and not share it with others. However, all this data makes Google a gold mine for governments, and giving out the data is not really in their control.

There are other companies that have business models don't necessitate all this data collection. When these companies have to cooperate with governments, there's a limit to the amount of useful information they can hand out about their customers.
