All sort of contractual gags that keep people from commenting on bad and sometimes malicious behavior. Because it's the only way to get the job they're trained for, etc.
Companies insisting on the contractual right -- in small and seldom-read print buried within a sea of other print, for an "everyday" purchase -- to essentially violate the 4th Amendment (I'm thinking; maybe I've got that wrong) against unreasonable search and seizure. I guess that right was targeted against the government, but it seems it should apply to these government-size corporations and multi-nationals, as well. Selling us what has become an essential service; try living most people's lives in the U.S. without a cell phone.
And hey, we know governments are making use of those data, as well. A typical government ploy; purchase data from a private, third party that the government is not allowed to directly collect, itself. Sorry, that "scrubbing" indirection shouldn't disqualify it from constitutional protections.
Divide and conquer. Whereas solidarity actually requires some privacy and wiggle room, to function effectively and autonomously in the real world.
