Facebook’s shadow profile of me does not even begin to hold a candle to Google’s shadow profile of me.

And Google has been monetizing that profile for a lot longer than Facebook has.

So while we're at it we should look at breaking up Google as well.

I only use google for youtube and cloud print. I'd like to break up with the latter but I haven't figured out how (history says google will force this in the near future). YouTube has a lot of great content (mixed in with even more worthless garbage) that isn't elsewhere, so I can't figure out how I'd break up with it.

On the other side, Google is tracking you on a lot of sites unless you use measures to counter it.

True. I wish there was a good way to stop that.

A good AdBlocker (like uBlock Origin) is usually enough. Also the tracking protection of Firefox is not bad.

A custom router can do this for all devices on your network. That is what I use.

Do you carry your router with you all the time to provide a bridge to mobile networks?

So what?

You can't break up with your stalker.

If Facebook is building a data portfolio of you, which is highly likely, then you can't avoid them, which means the problems that arise from the practice still impact you, whether or not you want them to.

Having information about someone is fine. It's not stalking nor harassment when you're privy to their location, where they live and work, everyone they interact with, their conversation, every newspaper and article they read, and every purchase they make. But it's creepy especially if this information is collected surreptitiously. Why collect this information in the first place?

It becomes harassment when this information is used to target someone. It is stalking if this information is used to follow you around. It is literally "cyberstalking" when it does. If someone is tracking you, they are stalking you.

Every website owner who puts code from Google or Facebook is complicit in this tracking/stalking.

When everywhere you go banners are being put in your face with messages tailored prod your fears based on what is known about you. When psychological tests are carried out en-masse [0], this is harassment.
