The desert Fremen of the first book were a tribal society where it doesn’t really make much sense to talk about freedom of speech due to the lack of any sort of formal government. But it seems likely that each naib makes his own decisions about how to run the sietch that he leads. How Stilgar is running Sietch Tabr may not be how every sietch is run.
It doesn’t talk too much about political conditions the city Fremen lived under, but the Harkonnens don’t seem to be too keen on civil liberties so we can probably make an educated guess.
In the second book, the Fremen have established a brutally repressive theocracy that is obsessed with rooting out heresy. Regular people being afraid to openly speak their minds about political issues is a plot point.
