Mugabe is a small time offender of this.
Erdogan the Islamist dictator of Turkey (our NATO ally /sarcasm) has huge lists of those who criticize him on social media. There never has been freedom of speech or the press in Turkey. Not even back in the Ottoman Empire.
Huge numbers of civilians are in jail in Turkey for just being critical of Erdogan.
He even arrested Amnesty International’s officials in Turkey for attending a meeting discussing security of communications.
Hopefully we can keep it in place, though there is a rising tide of those who cannot see the value of this right, and that right along with several others are constantly under attack. We continually need to fight back to preserve it.
Mugabe is no small time offender, he may not be as savvy as other dictators, but his regime is just as destructive to his people as any other on the planet.
