The problem with articles like this is that you can find equally good anecdotes from people who have rejected liberal feminism, some of whom previously identified as trans themselves. See /r/detrans for examples. They often describe their experience akin to being groomed by a cult, too.

Amy was connected to an international network of powerful lesbians.

Obviously exaggerated to scare the reader into thinking the GC movement is more powerful than it really is. Later in the article that secret cabal of powerful lesbians is described as "struggling" and "falling apart". So which it?

She believed that lesbian identity itself was being infringed on and erased by trans women, and that the media didn’t care – more than that, she believed that the media was being controlled by trans people.

Trans people don't control the media, but the liberal feminist view (that trans women are women) absolutely and completely dominates the media, as well as any organization devoted to LGBT rights, or pretty much any other organization for that matter. Dissenting voices are usually found on social media only, and receive severe backlash.

Amy's article denouncing the gender critical movement is published by PinkNews, which regularly publishes articles like this, so it's clear what the dominant ideology is. There is no major publication that would offer radical feminists a platform. So while it isn't true that trans people control the media, the trans narrative absolutely dominates the media.

The TERF movement won’t let lesbians talk about abusive women.

That's by definition not what the gender critical movement is about. That doesn't mean radical feminists don't think domestic abuse is bad; it just means they don't want their movement to be hijacked and its mission changed by people who oppose their views.

If abusive lesbians are such an important topic to Amy, why didn't she write her article about that? Apparently, she thought the gender debate was more important too. Hypocritical.

And though it may be true that the TERF movement won't let lesbians talk about abusive women, it seems equally true that the LGBT movement won't let lesbians talk about abusive transwomen.
