Is CNN promoting an overthrow of government?

No, not US government, Polish government. Several weeks ago Fareed Zakaria, host of GPS declared (several times) that new government in Poland (similar in a way they won to Donald Trump's) is turning "in the direction of a dictatorship" and that basically is a COUP.

Over the weekend, one of the CNN's hosts praised 3 days of street protests as a show of defense of free speech. Yesterday, Polish PM said in an interview: “This wave of hate which is pouring out, the omnipresent aggression, quarrels provoked one after the other, this is simply an attempt to overthrow the government and reverse the outcome of the election” of late 2015, in which PiS swept to power. (Does it look familiar?)
