The concept might be unfamiliar to you, but people don't abide by the same values as you do, and they can change over time. I prefer playing games on Switch (including third-parties) rather than my desktop PC because the versatility of the form factor suits my current lifestyle better. It's just a matter which device fits someone's needs and tastes better, and something like japanese games are virtually the same across platforms nowadays.
Being able to play a japanese game fully in its original language is something I value far more (even if I have to pay an extra 10€-30€ for an imported version) than framerate or resolution. You prefer higher performance and hacks on the other hand and that's alright, just remember though.
