Ghostery reports Omniture(Adobe Analytics) on the ACLU homepage, and additionally Adobe Test and Target on their donate page. On EFF, Ghostery only reports Piwik Analytics on their home and donate pages. For comparison, the NYTimes homepage shows 35 trackers. Personally, I don't have a problem with this. I am concerned about overreach in government policy, not nonprofits trying to learn a bit more about their support…
This is fairly off topic, but in case you cared, Ghostery's business model is to sell your browsing habits and blocked ads and blocked trackers data back to the people their extension blocks. They claim it's anonymized, and I'd venture to say it probably is, but it's still data about you.
This is surprisingly difficult for enterprises to keep track of. Different divisions might have different websites, or different campaigns running, and be placing things like tracking pixels or tags all over the place without telling anyone.
And embedded content can come with trackers of their own. For example if you embed a Storify feed in your site, you get 4 trackers with it. Surprise!
They'll host a page for the enterprise that lists out all the trackers, and gives visitors opt-out links for each one. Again--a total pain for most companies to try to do themselves.
It's all powered by people running the plugin, but the plugin data not what's for sale. At least, they never pitched me on it, and it's not part of their service description on their website.
