It's most evident in the games themselves, honestly. You'll typically pay an extra ten bucks for a game on the Switch compared to one on the PS4 or Xbox One, and part of that is because Nintendo uses proprietary cartridge technology that increases the cost to manufacture by a fairly large amount. If I recall correctly the cost to produce an 8GB game cartridge for the Switch is the same as a single-disk game for the PS4. The cost increases when you go up to 16GB or 32GB carts. This means developers take a bigger hit if they put more resource-intensive games out because they lose money on shipping.
But then there's also the issue of Nintendo (and developers working with them) being outright greedy. Selling games that weigh in at sub-500MB at triple-A prices is disgusting.
