"ICANN condones private auctions, as it has encouraged applicants to resolve contention themselves, presumably through buy-outs, partnerships, and auctions. ICANN offers its own auction model as a last resort. All proceeds from gTLDs auctioned off under ICANN's auction model will go to ICANN as "excess funds" that will be redistributed at a later date, in ways that are yet to be determined.[2] "
"The first ICANN auction of last resort was concluded on 4 June 2014 for the string .信息 which had two applicants. The winning price was $600,000 US Dollars. ICANN used their authorized auction services provider Power Auctions, LLC to carry out the auctions."
So looks like you are incorrect.
If we can get older blogs and new blogs onto the .blog namespace, then this will free up .com for what it was intended for; companies.
Also, I don't know that I'd call this extortion, no one is forcing people to buy up these new TLDs.
A cash grab, however...
