But it is not illegal!! Morals or ethics do not necessarily determine if it is legal.

It may not be unlawful, but institutions work best when there is stability of practice, even across leadership changes. Otherwise, you can’t do any long-range planning or undertake complex experiments or investments that could take years to bear fruit.

We used to have a shared sense of custom and mores that helped preserve this stability. But that seems to be out the window now, and regrettably so.
