Do you think any corporate isn't extracting data from you? Put techno companies to one side (as if not all companies are not actually tech nowadays) - what about pharmaceuticals, cars? All extractive as well as selling a product. Supermarkets? Financial companies? If you think there are companies not observing the data as well as selling the product, I don't think you're paying attention.
>Do you think any corporate isn't extracting data from you?
I think they are extracting and sharing data to varying degrees and that some have a business model which pushes them to one end of the spectrum.
If you take the example of supermarkets you used nearly all of them push loyalty cards which they use as a mechanism to manipulate your purchasing decisions but the one I frequent doesn't (Aldi UK).
Even in the example you use of a friendlier corporate, you have no idea what is being monitored. You only know there are no loyalty cards. You don't know if they are tracking consumers through the shop, over visits, etc. They do do that. They're not making a profit to do right by everyone.
