Of course in the case of Google, this only applies to the data the user knows Google has. Google does lots of surveillance, too, and that data is not included. But in any case, if you can get the data back, then you could track whether they have altered it. And they're not very likely to start altering people's data if the people can tell. So maybe we can keep a track on that particular kind of abuse.
