The presented line of reasoning makes no sense. But people aren't rational, that's no news.
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.
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 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.
This is not a good parallel. You can use any modern instant messenger like Telegram to talk to your friends as comfortably (or more).
I know Facebook is scum, but I have no other way to stay in touch with some of my IRL friends. So really I have competing agendas here, social connectivity vs. personal privacy, and I'm sacrificing some privacy to gain connectivity because I value one over the other. I, personally, mitigate the privacy loss by only sharing stuff I'd consider publishing publicly anyway, only liking stuff that's similar, avoiding groups and pages, periodically deleting all old content from my account, using adblockers and private browsing all the time, and customizing the FB web app via local scripts (thank you, FB Purity).
You can disagree with my values and the resulting choices (maybe you value personal privacy over social connectivity), but those choices are completely rational even for people who don't necessarily think about them in painful detail like I do.
So get over yourself and quit thinking that other people are somehow beneath you because they make different choices than you.
Other than this I don't use Facebook at all any more and have used it very very little for the past several years.
I use a browser that tries to protect me from trackers and ads.
To me, this is what makes sense to do.
But they still get a significant amount of my attention because I use Instagram though.
