I installed Ghostery just a few days ago, and it is clearly indicated that it is opt-in. I don't see a problem here, looks to me a bit like an attack against Ghostery. But of course, open-source alternative with the same functionality would be better...

I find Ghostery as a good compromise for me; Noscript is too much hassle for a day-to-day use, and I also don't like to use Adblock for "philosophical" reasons. Ghostery does exactly what I think should be done - remove the tracking, since I didn't give permission to anyone to track me.
