The right went quiet about censorship on X because there just isn't much of it. I remember at the time when people were asked to justify the claim X was censoring the left people could only cite three examples, two of which were mistakes and their profiles were rapidly restored (yet they were still being cited as examples of leftists who were kicked off the platform), and one of which was an Antifa account permabanned for ... inciting violence against the right.

In the Twitter years the right could produce endless lists of right wing people banned from the platform, and we now know there were tons of internal emails and discussions about that exact policy. The fact that nobody could produce similar lists for the left post-Musk indicates that he really has significantly improved the free speech situation there.
