There are a lot of things about which I'll get up over, and there are plenty of companies feted around here that I think are moral crimes in progress, but this isn't one and I think you've got the arrow of responsibility backwards. You're using websites and applications that have opted into using Facebook's infrastructure for the ends that benefit them, and as a side effect they are sharing the details of their traffic and users with Facebook. If that worries you--and I'm not saying you're wrong to be worried, though I personally don't care--you should not be using those websites. There are people who don't. I think their online lives must suck, but it's their prerogative.
I'm sure it's hard. But doing the right thing often is.
Your last point is exactly right: You can't choose not to use the vast majority of sites on the Internet.
Facebook isn't the only company doing stuff like this by any stretch of the imagination, but claiming that you can just "not use Facebook" if you want to avoid them is complete nonsense, hence my original comment.
How do you know, and thus conciously choose, if a site has a facebook widget without visiting it ?
You could use adblock or something similar on the desktop or android, but then you need to know about it first, and it opens another can of worm regarding site revenues etc.
Also if you're an iOS user you'll just have to live with it or abandon Safari for more limited browsers, and avoid opening any webview from any app ever.
Avoiding sites that use facebook widget is just not realistic. You're fine with it, and that's ok, but that's not really the point.

Black-hole everything coming from a Facebook domain?

Convenient, then, that I don't use iOS. (I use Android, and I do have an /etc/hosts file to kill some things I don't want to see.)
