Ask yourself this: Would any of those people think twice about violating my privacy?
My high school had no qualms about searching my locker or my bag. My ISP does deep-packet inspection and will hand over my logs to any LEA that asks, without a warrant. Practically every company I do business with resells my data in some way, to their benefit and my detriment. The vast majority of institutions have no respect whatsoever for my privacy, so I have no respect for theirs.
