Here is a metaphor that you may be able to relate to: If I send a postcard by snake mail I take the risk that the postman will read it even though he is forbidden to do so by law. Since he has to look at it in order to find the delivery address, reading some of the text may be unavoidable and nobody will try to make a case against the postman.
However, if said postman makes a copy of the postcard, takes it home and stores it in a box THEN he is facing criminal charges. And this is exactly what Google did.
