For those of us living in the privileged western societies, we can of course replace Facebook with something else. But that something else is just going to end up in the same place, because the content provided by these services is financed by marketing money and it's crucial to keep that going - because of quarterly economic reports and the stock market - it's a vicious circle we've created and now have to keep feeding.
In other parts of the world, Facebook is synonymous with Internet access. They don't use computers - Internet is mobile - and Facebook offers free access to that mobile network - if you sign up with them and use their apps, of course.
It's the worst kind of digital colonialism you can think of.
Nothing has changed in the world - the Internet didn't make information free. We in the west are still slaves of the system - and we're still exploiting the developing world.
The only sensible move is not to play. The only way to fix it is to change the system. But we're not going to do that. We love our toys.
