If I'm not putting words in your mouth, and maybe I'm just projecting here, but I think the disturbance you're expressing stems from the imbalance inherent in the idea of a faceless corporation and their semi-autonomous mechanical agents (code) having access to intimate, personal knowledge of you while you have no access to knowledge about them. This is compounded by the motivation being to extract money from you. If a friend knew and felt your sleep pattern was problematic I'm sure you wouldn't mind - in that case personal knowledge is reciprocal, voluntary, and not motivated by money.
