You’re still allowed to say virtually anything you want if you make it clear that it’s an opinion and not news reporting.

Not citing sources doesn’t imply plagiarism, as long as you don’t misrepresent someone else’s research as your own (such as in an academic paper). Giving an account of news that you heard elsewhere in your own words isn’t plagiarism. The hurdles for plagiarism are generally relatively high.
