I kind of expected this...
Why?

I expected it too. I've been saying ever since the UN Resolution against insulting religion was passed that its really an attempt to give the green light to oppressive regimes to silence dissenters among their own people. That's why China and Cuba supported it - they don't give a stuff about religion, they just want a handy catch-all law to lock people up for speaking their minds.
Even in Iran, where the authorities probly do care about religion, this law will be used to punish anybody who criticises the government under the excuse that they are criticising Islam.
Expect to see more of the same in other countries in the near future.
