Galileo's book was censored by the church because it insulted the pope.

I'm not certain if that exists much today. Similar censorship would be curtailing mockery of public authority figures.

Everyone who uses Twitter has seen the little ! triangle saying a tweet has "misinformation". Or read about people suspended for discussing

- Possible therapies for COVID like ivermectin or HCQ

- Claims that the 2020 U.S. presidential election was swung via fraud

- Hunter Biden's laptop [edit: had D. Trump here but that's covered by above]

I'm fairly confident that you have, yet have decided to be obtuse. If you haven't then maybe you aren't the right person to opine about censorship on Twitter.
