Bullshit. Those can be sources, but they are not journalists. I beg you to look up what a journalist does, because you clearly do not know it and you're making a fool of yourself. Doing journalism is not as simple as saying "This thing happened".

A person with a smartphone does not do research, does not interview people, does not spend all day working on a story, does not have the support of other people whose job is to know stuff, does not try to understand what the implications of something are, does not have a code of ethics, etc etc. Journalists spend 100% of their day working on a story and that makes all the difference in the world. It's a job with specific duties. " Citizen journalism" is not journalism. YouTube personalities are not influencers. People researching stuff in their free time are not journalists.

Recording something with your smartphone and posting it on Instagram does not make you a journalist, just as me cooking pasta for lunch does not make me a chef.

And that's because - again - doing something for fun or by accident is very different than doing it as a job. I guess your skepticism may come from not yet having encountered good journalism, and I'm sorry if that's the case. My advice is just to keep looking for it, because finding a news org that you can trust makes all the difference in how you can understand the world.
