This issue really separates the wheat from the chaff. The dirty secret is that a lot of academic published work contains errors but the authors also have fragile egos. It reminds me of when Data Colada exposed someone for fraud and they accused the exposers of "methodological terrorism" (something in psychology or social science). Just imagine what happens once papers get exposed at scale.

Now here there was no fraud just genuine error, but it will annoy people nonetheless and scrape their ego that someone uninitiated can just type some stuff in a magic box and conclude that they, the established published, tenured mathematician with awards and medals can be wrong.
