Aren't there any devs left on this site?
I'm all for privacy, but if:
* I'm running some site
* someone (a bunch of people) embed an image on their page that hits back to my site (or a service I offer)
* I log that shit cause those users are hitting my servers
IMO, if anyone should be dinged here, it's those sites that are embedding the trackers without notifying the user that they'll be sending the users browser off to umteen different external sites.
Browsers can also be configured to aid with this. For example, the option "Block third-party cookies and site data", aka "from originating website only". I believe that used to be available for images as well.
Users also have multiple options to control what the computer they own does online. For general browsing, solutions vary from browser plugins (AdBlock and friends), Proxy based solutions, hosts file modifications, local DNS server, firewalls, etc.
FWIW, I do NOT think sites should be encouraged to evade these options. As long as they're using their domains on all those tracking things (which, as far as I can tell, they are), then I don't see the blame falling on the service provider. Don't want them to get your hits? Block them (facebook/twitter/google/linkedin/etc), or don't use sites that do that to you. This level of legislation seems to go a step beyond the "don't post links that point to sites that host copyrighted works", which no one in their right mind agreed with.
