I think Facebook is the most evidently intrusive. They monitor all of your online activity pretty much and then shape your thoughts and such with targeted advertising.
If you're that easy to manipulate and a few ads can shape your "thoughts" even billboards are dangerous for you.
The problem might not be the website, but the user behind monitor.
You're implying in this that I'm incapable of speaking for the majority of the public instead of myself. And also that all statements are absolute, your thoughts could be influenced but not completely.
You must have heard about this article right where
facebook was doing experiments on manipulating emotions. We have to accept the fact that not everybody in the world has the same level of smarts and common sense. Their are a lot of emotionally unstable, emotional fools out there. That doesn't mean that the intrusion by ad companies is answerable by the individual himself.
Also we must accept that there are a lot of easy to manipulate morons who will make the wrong choices.
Hitler was voted by 30% of the Germans, and Stalin would have won fair and square every election.
And this was way before Trump and whatever happened there.
I wouldn't even necessarily say that 'idiots' is a fair judgment. It's not that they are incapable of making good decisions for themselves it's just that they either fear doing it or are too lazy to do it. They accept the information that is most readily spoon fed to them by the world.
