The first few times I've visited Diana Allers in her cabin, I've had the option to kick her off the Normandy:
Recently, she argued with a crew member about whether or not to run a story and I took her side. Afterwards, I found that the dialogue option to kick her off the ship was no longer available.
Does supporting Diana mean that she becomes a permanent part of the crew?

You will eventually reach a point where, upon talking to Diana, she will simply say, "Shepard." As soon as that happens, choose to talk to her again.
You'll be met with two options upon doing so:
That will be all. or Get off my ship.
Simply choose the latter and Allers will leave. And take her horrible voice acting with her!
