I don't know.
This whole episode certainly reflects very badly on PSF SC. But it is not a very glorious event of Peters' life either, and it feels better to just not uselessly stir the pot in a way that makes Peters not look good.
(and again, to be clear, PSF SC looks even worse, but of course the point is to remember Peters for what he was, not to profit of his passing to score points against PSF SC)
Python leadership threw him under the bus and now it's all nice obituaries pretending nothing happened.
