Ironically this is actually an example of Valve using its dominant marketshare to suppress rivals - Steam’s ToS require devs to have equivalent pricing across all storefronts if they want to sell on Steam at all, so making it harder for cheaper storefront cuts to translate to lower prices to consumers, who might otherwise move to a different storefront.
Devs aren’t going to drop Steam as a store, so they’re stuck.
Steam’s “price parity rule” is a policy that ensures that Steam keys cannot be sold on other sites unless the product is also available for purchase on Steam at no higher a price than is offered on any other service or website.
