Yes, I find it odd that Google gets so much attention while Facebook never rates a mention. I find Facebook way more creepy and actually much harder to switch away from - I can use bing any day of the week and the results are comparable. I can use G+ today and the results are useless. To my mind there has to be some recognition of whether a "monopoly" is due to exploitation of natural barriers to entry or not, and Google seems one of the least problematic in this regard.
