No it wouldn't Because there is no such thing as free lunch. Somebody have to pay for these satellites.
And it is quite easy for authoritarian government to prevent its citizens from paying to the satellite owner.
Note that Bitcoins is already illegal in Russia.
So, owner of these satellites would have three choices
1. Adhere to censorship rules
2. Don't service any people in these countries except few who are brave enough to use some criminal payment scheme.
3. Get some foreign government to pay for free access of users of particular country as part of information war against it.
I don't think that variant 3 gives much freedom to users.
Moreover, Internet is bidirectional by its nature. So, every satellite modem has to transmit some radiowaves on some particular frequency. And this signal have to be strong enough to reach nearest satellite (which is not less than several hundreds kilometers away). So, law enforcers would be able to detect such transmissions using ground-based equipment, which is lot nearer to the transmitter (they don't need to decipher contents, just locate transmitter) and seize modem.
