That only works at a certain latitude. Further north it remains dark in the morning anyway

I'd rather have sunlight when I get home off of work to be able to do stuff outside before it gets way too cold and dark. In the mornings before work I typically don't go outside so it can be dark

I've found people would either like change or not mind it.

But like you said, they can't agree on which way so thus it is.

I honestly dgaf about any of it. I'm fine with the current system.

Yep. A lot easier to have blackout curtain in just your bedroom to stay asleep than it is to have them all over your house to build up melatonin in the evenings during summer
