GNU Project or FSF has nothing to do with it, the guys of GNU Boot are only associate members of FSF.
Libreboot.at itself seems to be a reaction to binary-blobs, not to this other drama.

Unless there was a third "abandonment" and a "takeover" after that, I don't see how those events are related. Once again, happy to be corrected.
A project cannot enforce FSF-owned trademarks if the FSF "has nothing to do with it."
I suspect you know very well that what you said is false.
That's not a better question at all. They list out their explicit reasoning for their attempted name takeover. I definitely don't agree with it, but I have no reason to believe that they're lying about their own beliefs.
I absolutely do have reason to doubt Leah's words of releasing GNU Boot as being in good faith though. Their history of drama with them is the reason for my doubt.
In terms of practicality, I feel like a better reaction would have been to either trademark their project name or maintain a separate fork of Libreboot that would include the binary blobs. Why resort to trademark infringement?
Whatever you may think of Leah publishing an unofficial GNU Boot release for them to rebase off of, she didn't try to impersonate them by buying a confusingly similar domain.
Compare her single reference to an "unofficial GNUBoot release" to this: https://libreboot.at/
