When we got together this was not even negotiable on either side, we basically laughed at the idea of a single blanket.

I did suggested a single mattress to not have a gap but got a simple no and didn’t ask again.

Objectively,

Because we would be avoiding the 2 jet lag times a year which have been proven to cause deadly (traffic) accidents.

Because the other alternative of always dst means sun only gets up at 10am in winter which can negatively impact mental health (especially for children and teenagers)

Subjectively,

Because some people actually enjoy summer nights.

Because getting up on time is easier with more sunlight. And waking gradually and naturally at 5:30 beats waking forcefully by alarm at 6:30

How far north do you live to get darkness at 3.30 pm?

Its also not a choice between ops pictures and this because i am convinced they are criticising daylight saving In summer, which does not affect winter.
