I’d be flattered to be able to have the answers for all of these questions. Delivering a workable solution for an enterprise with 4billion approx users and parent worth several US$ trillions though should be trivial. It simply needs to see a benefit in doing so. Reward or penalty or both.
Google, Facebook etc have all seen the pathway to monetising the delivery of their services. They have promoted the benefits and good of doing so, and taken the profits. When it comes to the not so good outcomes why should we consumers take on the responsibility and costs of fixing the bad that comes with what they have created? Credit given where credit is due.
