I actually consider this acceptable. I may begin using forbes again. I would briefly turn off adblock and then reload it if the data/article wasn't obviously available elsewhere, but I would let them have my basic google data to read an article.
It doesn't make a ton of sense for them though, right? I mean that would just verify through google analytics that a real user is reading their article and maybe some basic demographic information which could be pitched to advertisers...oh wait, they also verified these users won't run malware on their systems.
The only way they could seemingly benefit is if someone clicks the around the web links at the bottom, which again I consider fair play.
