Once something like Facebook Messenger has reached a critical market share trying to get people to stop using it
writing this comment from South-East Europe where many people use facebook not just for cat pics but to find work and network with colleagues. It's a huge problem in developing countries where facebook IS the Internet. FB recently announced it would roll out job-posts for low-income workers[¹]. This will mean an even stronger lock-in for the user. While the discussion on ethics evolve mostly user-privacy and CA/FB role in Brexit/election hacking, the problem for less developed regions is facebook taking from them without giving back (fb is known not to pay it's taxes in Europe)
Echoing your statement, "Facebook is the Internet". In Africa most telecoms have special data bundles for Facebook and WhatsApp. Normal data bundles to browse the Internet are just too expensive. A dollar will give you unlimited access to Facebook and WhatsApp for about 2 weeks.
I have a few cows back in my village. I have toyed with the idea of creating a cattle monitoring application that would have to make use of Facebook or WhatsApp. The herder sends me a picture every evening of the cows. I want to piggy back on the affordable connectivity given to Facebook and WhatsApp. Yes I know, this would contribute to the problem but for me losing cattle is a bigger problem. From parent, finding a job is a bigger problem so we all get sucked into Facebook.
