My friend from Germany told me that in some (but not all) the pages, there are dummy social buttons loaded by default, you have to "enable" them. Try any article at [1]. It actually displays grayed placeholders only [2], and things are fetched from G/T/FB only when you click it - you can see in HTTP console.

and a couple of others (fbcdn, facebook.net etc.).
I could spin up a VM and route the FB or non-FB traffic through a proxy, but I haven't reached that point, yet. (Probably, foolishly and to my detriment...)
P.S. In other words, state is already stored on their servers, not (or rather, in addition to) your browser.

Obviously, rulesets should be tuples of (source pattern, resource type, destination pattern), not silly lists ("allow google.com", huh?) like most browser extensions do.
However, there are some sites that stupidly execute JS that is vital to the running of the page after attempting to initialize Google Analytics or other services. The end result is that they get a "Cannot call method 'bleh' of undefined" error which prevents the rest of their JS executing, hence broken page. If I'm really interested in actually loading the page, then I have to resort to allowing the trackers to run. sigh.
Unfortunately, I can't see how this could be averted, stopping short of an extension which catches all uncaught exceptions, then tries to forcefully remove all JS which is meant to interact with 3rd parties. It could be done either via pattern matching, because Google Analytics code looks much the same on most peoples sites, or it could be through something more fun, like https://github.com/mattdiamond/fuckitjs (who would of thought there would actually be a proper use case for something like that??)
Neat. This looks like a very reasonable way to go if you decide to have social buttons.
Is there a ready-made solution for this?

I'd be interested in learning about good alternatives.
For example:
- https://www.facebook.com/sharer/sharer.php?u=[Url to share]
SocialCount looks like it also cares about how many times a link has been shared, and uses a server-side script to figure that out. That seems like a nice approach if you really want that info, because it doesn't let the social service track the end user.
shareNice seems to have a wider range of services that it supports.

The suppliers of said social buttons do; every time you see one while you're logged into FB / G+ / Twitter, a hit of you visiting that site is registered at said parties, and they can all, thanks to the prevalence of these sharing buttons, track your internet usage.
