Nooo. Don't worry. It's to bring down spam. And the best thing: funds go to the Ethereum foundation to heal brain damage of the trapped in Vitalik's scheme.
There is a community censorship mechanism: flagging posts. If a post gets sufficiently flagged it will be labelled "outlawed" and only those who opt into seeing outlawed content will see it.
As others have said, the post costs are intended to reduce spam not real speech.
I reported a similar issue to @k00b and he told me there was a glitch making the displayed post cost 100 even though when I checked I had only been charged 10.
