Comparing Facebook to alcohol/drug abuse is like comparing piracy to theft - it misrepresents both issues while making it more difficult to discuss their impact and ways to solve them.
Instead of calling people addicts, it'd be better to give them an actual compelling reason to stop. Hint: that whole privacy thing is not good enough of a reason.
So instead of heating your own food, or finding someone else to heat it - they demand politicians to intervene - to make sure Zuck - and all future food heaters - are properly blindfolded to respect your delicate sensibilities.
My fear is for the future of food heating technologies that don't involve Zuck. Hint: All the rest of them.
One could certainly stop stop Facebook, WhatsApp, Twitter, Snapchat and so on. But you'd have to consider what the impact is; maybe you'll become more distant from friends and family. Maybe you'll miss out on events. These things are pretty important, for obvious reasons, and it's a shallow argument that everybody can simply walk away "instantly with no ill effects".
It's up to the individual to decide if the trade off is worth it. Clearly, for some, it is.
I certainly made no proclamation as to how anyone should live, which you seem to have mistakenly inferred. I suspect that level of unprovoked defensiveness to have an interesting underlying cause.
