Yes, but that's not how it's defined.
"Fiat money" means that it's a monetary system created by laws passed by the government, and any attempt to use something different is enforced by law (aka violence/theft/kidnapping etc)
The fact that the supply is manipulated by the Central Bank to enrich their friends, (not just Government cronies, but more significantly, their corporate crony friends too) is just a byproduct of the fact that government system forces people to use Central Bank created money.
Bitcoin is free market money really (contrary to my earlier assertions in this thread, which played on the article's inability to correctly identify the meaning of the word "fiat"), where the aggregation of people using it in trade and exchanging it against violently dictated fiat money determines it's value, not by some tiny number of rich over-privileged traders on the FX trading exchanges.
We live in a communist system really, folks. Privatised communism, but not capitalistic. Capital doesn't determine prices in this system, a violent uber-class does.
