Private data of users is stored by service providers.
Learning of user data/behavior is done by service providers
Users generally have to sign EULA, after which (the ownership of

Service provider sometimes provide in exchange access to free service.
Eg: Google mail or search etc
Many a times users do not control their data and is traded on their
behalf by third parties. Eg: Google bought double click for user data
Users do not control their data and are not a part of value chain when

their data and have a control on it.
Users decide what to lease and what not to lease and at

They will have to pay to OtaSizzle platform for participating in
this kind of posting. This earnings can also be passed on to
users in form of discounts.
