Given that hate speech is constitutionally protected, why was Facebook able to change its terms of service to prevent users from posting hateful commentary and claims?

Because Facebook was not exclusively targeting right$-$wing or left$-$wing groups.

Because it is a private company, though Facebook's actions may one day be challenged in court.

Because the Trump administration declared Facebook's actions were not in violation of free speech.

Because commentary and claims made in social media platforms cannot constitute "hate speech" under the Constitution.
