>Yuzu impacts their bottom line in a way that Dolphin doesn’t.
Dolphin could emulate nearly all commercial Wii games by April 2009.
That was sooner into the console's lifespan than where we are now with the switch. (29 months since the Wii's release vs 83 months since the Switch's release)
Maybe more people have gaming-grade computers sitting around now than they did 15 years ago?
