Do you think social media represents a true public forum for all individuals where speech can be expressed freely without repercussions, particularly for journalists who report on the news through their social media postings?
For example, recently, Elon Musk temporarily suspended the accounts of several reporters from his platform because they violated the platform’s rules banning private jet trackers, which is when reporters share the tracking of private jet’s flight plans, including one that tracked Elon Musk’s private jet.
Does social media have a right to suspend or limit the posts of journalists? Is it comparable to the US government regulating or restricting journalists’ speech? Should the government be allowed to direct social media to suspend or restrict the accounts of journalists for messaging?
When answering these questions, please offer an example to illustrate your point (please do not use the example from above).
