I have found a couple of responses to it:
"Pity it didn't run but with an explanation why no interviews with them published. TV news run items which say 'we asked X for their point of view but they declined to comment.'"
"In the US, articles are pulled at major outlets regularly because an editor decides, at the last minute, dissenting voices on trans issues cannot be aired. At least you're talking about it so ppl KNOW the censorship has taken place. US reporters whose stories were pulled keep mum"
""Pressured" how? Perhaps you mean she convinced them to pull out by the cogency of her arguments?"
So I didn't dream it, but the tweet is gone.
