Book burners don’t have any morals, they just want to burn books, and they’ll come for yours sooner or later.

They're not book burners... they're just trying to eliminate certain media they find objectionable? They would consider it unacceptable for Steam to, for example, make these items only purchasable through crypto/bank transfer.
Okay, since you stated it as a fact: Citation needed. Show me Visa’s statement to the effect that they have no agenda, because all of their actions suggest otherwise.
