I think it's because when people do a 180 due to public pressure, it's hard to know to what degree they changed their mind and to what degree they are just lying about what is on their mind.
Toning down aggressive phrasing is not "doing a 180", calling the change from "only losers left at GitHub" to "the engineering excellence has left" lying seems disingenuous.
> I often find we don't appreciate enough people accepting their failures and changing their mind. For some reason I see the opposite: people respecting those who "stick to their guns" or double down when something is clearly wrong.
