Twitter bans Trump, but Iran's FM who executes journalists, protesters & gay people still active on platform

Twitter sparked major controversy with its decision to ban President Trump from its platform, citing a risk of "further incitement" following the violence that overtook Capitol Hill. The tech giant has come under fire, however, for the glaring exceptions they appear to have made for some of the world's most hateful and dangerous voices, notably Iran's supreme leader, Ayatollah Ali Khamenei, Iranian President Hassan Rouhani and Iranian Foreign Minister Javad Zarif.

As you can see in the posts embedded below Iran systematically executes innocent people including human rights activists, journalists and protesters.
Over the past year Iran's terrorist regime has executed Rouhollah Zam, a dissident journalist a year after he was kidnapped by the Revolutionary Guards from Iraq and forcibly repatriated to face trial.
Iran also hanged champion wrestler Navid Afkari in September after he was accused of taking part in anti-regime protests.
In Iran's prisons there are more than 7000 protesters on a death row after they were arrested during mass protests in November 2019 when 1500 protesters were shot to death in the streets, including hundreds of women and dozens of children.
How come Twitter embrace the worst human rights violators in the world but can not tolerate Trump and his supporters who are simply exercising their rights to freedom of speech and freedom of thought?

The execution of wrestling champion #NavidAfkari for simply exercising his right to freedom of expression should remind the world that the clerical regime which governs #Iran is barbaric,cruel & evil. https://t.co/DnNPVoPo3g

1-Calling EUROPE: Today, the Islamic Republic executed Iranian journalist, #RuhollahZam, who was kidnapped by the Revolutionary Guards from Iraq. The clerical regime kills Iranian dissidents as it takes Western hostages to use as pawns. pic.twitter.com/aPgW5XpmTJ
