There's definitely a pile-on effect happening. Consider that story about click fraud a few weeks back. As far as I can tell click fraud isn't any worse on Facebook than it is on any other ad network, but they took a disproportionate amount of heat.

I think it's a combination of the over-priced, under-performing stock, advertisers realizing that fb isn't that great of an ad platform that makes the shine come off of FB and make stuff like this seem less acceptable than it would have just a couple months ago.

If we're thinking of the same article, it wasn't about click fraud, but rather a unique-to-Facebook class of users that heavily devalues click-throughs on Facebook ads.
