By outsourcing these services to privacy-invading data-collection companies that make their money from advertising (e.g. Google, Meta etc.), we are in effect selling are data and our user's data to these shady companies, and often for nothing (or worse, we pay them for their tools).
Additionally, their TOS can have clauses that result in us giving them permission to let their AIs consume our content and data, which itself can cause our data and content to become worthless (e.g. since someone can just get the info/answers by asking an AI rather than accessing our website or buying our content).
Once you.pw is secure, we can then use you.pw's services to verify identities locations, and phone numbers and such for OnlineBookClub and any other products.
