Not just "shady" jobs! Any company including the large tier one's doing "big data" are harvesting data by various questionable means for questionable purposes.

Not just "shady" jobs! Any company including the large tier one's doing "big data" are harvesting data by various questionable means for questionable purposes. After working temporarily in big data at a large unnamed telco who has a monopoly my home internet is locked down, vpn'd, dns going out over vpn + over tls and the ISP provided modem straight in the bin as it's untrusted where ISP's can push updates when they want with what they want. One prototype may be performing a network scan for unknown to the telco mobile phones who are on a different provider so they can up sell mobile+bradband packages! Likewise your insurance company offering health monitoring devices for free discounts or car tracking devices to reduce premiums is not for your benefit! The only benefit is to a) Figure out a way not to pay out or increase a premium, b) re-sell the data to other 3rd party companies for further $$$. Big data is the most soul destroying, meaningless job i've worked in, often going own questioning the meaning of life!
