It's because devices have been pushing these system preferences. At one point I believe MacBook Pros were coming with default dark mode(or at least asking you which you prefer during startup). My phone auto switches to dark preference based on time/environment. Now, you don't want to be the ONLY product your user uses that blasts their eyeballs out because it doesn't respect system preferences.. Do you?
