The Switch was always sold at a profit relative to its hardware component and manufacturing costs, yet Nintendo charges 30% platform fees just like Apple (and Microsoft.) PS4 and PS5 (disc model) are currently sold at a profit, and Sony continues to charge the same platform fees.

Nintendo (like Apple) needs to recoup R&D and software development costs, and their business model is based on charging platform fees.

It's completely unsurprising that Apple's gaming handheld uses a similar walled garden/platform fee business model similar to Nintendo's.
