I know how Valve's publisher API works, others are similar in case you didn't know. But that is only true for games that need online validation of some sort, DLCs for offline games don't need to implement this.

Valve is hosting the game, providing the storefront and bringing in a lot of customers. If you didn't think those 30% were worth it you would not have put your game on steam.

Plus all of this is irrelevant to the point that Valve doesn't enforce price parity.

For the base game, which I think 30% is still more, I think it certainly makes sense. Because they're providing a complete solution.

For in-app purchases or unlock purchases, whether or not the purchase is in-app, the solution isn't complete, and not worth the 30% they charge on those transactions. It would be trivial for every transaction to have a custom field where you could store an array of what was purchased in in that purchase and have it returned when the transaction was checked. Boom, complete solution. Specifically for in-app purchases if they wanted to take 5% since all they're doing is the job of Stripe and nothing more, then I'd consider that fair.
