When Mr. Musk purchased X in 2022, he promised to create a free speech haven and named himself a “free speech absolutist.”

Critics still feared that Mr. Musk would use his control of the app to pick and choose his favorites, amplifying voices he admired while suppressing people or topics he loathed.

The New York Times found three users on X who feuded with Mr. Musk in December only to see their reach on the social platform practically vanish overnight. The accounts are the starkest signs yet that Mr. Musk or others at the company have the power to punish critics and that they may be willing to use it, startling free speech advocates who hoped that the billionaire would be their champion.

Concerns about Mr. Musk’s influence have grown alongside his political ambitions as one of President Trump’s closest allies. He has also set his sights on boosting far-right politics across the world.
