As with most news organizations you must be cognizant of the difference between Opinions / Editorials and actual news.
Most news organizations have slanted viewpoints when deciding on which stories to cover and which to ignore. You also have to take into account the sources that news organizations sometimes use.
X has no credibility because like all social media platforms they give any and all nut jobs a platform for their own personal agendas and profits. All with out the slightest hint of journalism and ethics.
As always each person has to make up their own minds. My problem with this argument is calling any social media platform or even late night television or podcasts journalistic outlets. They are speech outlets but not journalistic outlets.
Some of the problems with social media.
One-sided news
Inaccurate news
Censorship of the news
Uncivil discussions about the news
Harassment of journalists
News organizations or personalities being banned
Violent or disturbing news images or videos
