and nobody was forcing her to stay in that hospital, or stopping her from travelling elsewhere for treatment, that just isn't true

Thanks for letting us know this. The stuff I was reading about it said that the doctors had ordered her into palliative care against her wishes and the wishes of her family. It made it seem like she was under the equivalent of house arrest.

That really makes a difference in how I see this. If she was able to leave but chose not to, then that's on her.
