If she earnestly believes that particle physicists are lying to the public to get funding, then there's nothing malicious about going to the public and saying this. It makes her essentially a whistleblower, and there's nothing malicious about that. Even if she happens to be wrong, that still isn't malicious intent.

If she's lying, then that's different. But I haven't seen any convincing evidence that she's lying. It's clear a lot of people don't like what she's saying, feel threatened by what she's saying, and think she's wrong. But that doesn't make her malicious.
