These products already do what basically everyone wants them to do. The problem is now people are conditioned to having their privacy violated so they are still the product and they will pay to be the product. The network effects with a product like WhatsApp are strong so that this opens the door to dark patterns for the non paying customers. After enough time the same level of effort will go into the now subscription app that went into it when it was free. YouTube is a good example of this phenomenon.
