Removing her from tenure track prior to her reasearch gaining traction may have been short sighted but excusable - more an embarrassment than anything.
Not returning her to tenure track once her research proved fortuitous is much more concerning.
Trying to take credit now for facilitating her research when they actively worked against it at the time is damning.
All of this seems to be normal in most universities. I have seen my PhD advisor's video for a TV channel recorded, later presented in TV with his face cut off and another Professor (unrelated to our team) explaining it on TV. The response from the TV channel ?, We signed off the video rights to do as they please with them.
