Blame both laptops and consoles. The reasoning is the same: both have less powerful hardware and developers want to maximize the availability of their game.
I'm not sure laptops account for a lot of the choice, when designing games, to be honest. Consoles, sure, there's a market and a reason to take them into account.
But you don't really have many AAA devs planning on running their game on laptops.
