If you don't mind sharing your private conversations then sure it starts looking rational.

It is not just an ideological battle when your information is used directly against you personally. Companies pay for ads targeted to you by mining your personal content.

If you are not on facebook or rarely use it they have no opportunity to influence you.

You can use Facebook while not having any conversations on it you'd wish to stay private. I think most of my friends still on Facebook use it that way.

Facebook is a contact point, first and foremost. Nothing prevents you from greeting a friend and requesting that the conversation continues on a more private channel.

Yes. There are many options outside of Facebook, but compromising your morals sticks with you.

You don't need FB to comfortable communication with friends.

So there is no reason to use it.

If you know what FB is about, and still use it nonetheless (actually for no reason), that's highly irrational.

"I want to communicate with my friends" is just a very lame excuse for feeding the machine.

> You don't need FB to comfortable communication with friends.

You don't need planes to meet your distant relatives, but flying is often much more convenient than other modes of transportation.

> So there is no reason to use it.

Convenience is my reason. If you don't have reasons for yourself, that's fine, don't use it, but don't say for everyone.

> feeding the machine

This is a bit dramatic.

>You don't need planes to meet your distant relativesx

This is not a good parallel. You can use any modern instant messenger like Telegram to talk to your friends as comfortably (or more).

It is a good parallel. Obviously if your relatives live on another continent, flying is the optimal, but for example you can ride a bus from SF to LA instead of flying.

Bus takes much longer, whereas other messengers are practically as convenient as Facebook.
