It's not an overstepping at all, reddit has and always will be authoritarian. They will always be political. They banned whitebeautyart because it invoked a feeling of honor, tradition.
They won't ban antiwork because it encourages giving up, consooming, laziness, weakness. Exactly the kind of NPC audience reddit milks money off of. Ad revenue, reddit gold, buying emojis, constant scrooolllling, etc.
You are just naive, there will always be authoritarianism, forever. You're just on the receiving end or the administrating end.
