Most organizations that I am aware of do not seem to have term limits on their leadership team positions, but particularly in Amsat-NA's case, it might be a good idea to add terms limits as an amendment to the bylaws. The bylaws are here: https://www.amsat.org/bylaws-of-the-radio-amateur-satellite-corporation/. Not that I would expect it to be easy to get agreement of 2/3 of the directors (see Article IV near the end of the page). Members might go for it though.
I could find nothing mentioned about any kind of limitations of being a director or executive, other than being elected. So in theory, someone could be president for life.

This dilemma is quite common with clubs and organizations.
It's the apathy of the general membership that allows this happen.
Nobody seriously campaigns or perhaps even know enough about the club operations to get elected.
Sometimes, its due to a form of intimidation from the entrenched leadership.
None the less, if things get to where they are now at AMSAT, you would think the member would elect ANYBODY to replace the current regime, but that didn't happen.
I think you gentlemen are beating a dead horse, unless you are willing to continue waging a reform campaign with facts, figures and a plan.
There was a guy who had an agenda to bring to the ARRL, who showed up at every hamfest I attended , ( probably all in the district) handing out flyers about his plans, asking to be elected district manager.
It was a success. He unseated a "do nothing" manager of 20 years.
There is hope...
