"We put lots of engineering effort into mining your personal data and selling bits to other people, but we can't be bothered to put any engineering effort into disclosing on your profile or account-settings page what we're doing with your data."
A lot of the questions are answerable generically (no differences between users). You can't tell me that writing a data privacy FAQ with those answers in clear, simple language, once, with a link on every page and on users' profiles, is an excessive burden. These companies just don't want to have even that minimal burden and process to ensure that changes in usage of personal data get documented and updated on such a faq.
