I completely agree. I don't use FB although I do have an account for a couple of reunion groups. I won't install it on my phone though. But the amount of data collection across the board is incredible. Not just FB. I've gradually started to move away from Google products, already use Linux, and am probably going to get a VPN to limit as much collection as possible. My use of Android is a problem and the only real solution is to move to an iPhone instead. But I'm not sure whether that's a complete solution either. I'm not tin foil hat enough to get rid of a smartphone but I do want to limit it in areas I can. Youtube is a problem because it's linked to Google. But once I stop using gmail then I can probably just create a completely new account just for that.
I was one of the archetypal micro computer geeks and an early technology adopter. But the direction we are going in is quite scary. There is face recognition in some parts of London and I can see a cashless society and completely automated cars in my lifetime. Once they arrive then your every movement will be tracked and may even be blocked if you don't have enough social credit (such as one particular country already does).
Scary times, but we all just accept too much surveillance in exchange for the shiny shiny things technology brings us.
I'd switch to Linux if I didn't game on my PC. I know that running Windows games under Linux has become much better, but it's still a case of little over half of games running to a playable extent with an acceptable degree of inconvenience.
You can use Youtube without using (or even having) an account for it. I do. Google could stop that, but at the moment it has decided that it doesn't have enough dominance in that area to be certain of getting away with it.
I'm just glad I'm old enough to probably be dead before it gets much worse. Because it will get much worse. Power tends to corrupt and the greater the power the greater the corruption. With complete control over everyone's movements, employment, purchases (even if they have enough money) communication and even gestures (since those will be automatically monitored too), great corruption is pretty much inevitable.
