The web needs to shift more to a model where people pay openly for services; ideally with micropayments or a Spotify-like subscription to ensure a large user base. Free products are ok as a gateway to the paid product, but not if the business model relies on selling data (either directly, or as in Facebook's case selling the processing of data).
