Don’t threaten me with a good time.

Or is it more of an age-gated thing

Depends how old you consider old, maybe? Computers back in the day were pretty universally light text on a dark background. VIC-20 was an exception but then even Commodore backpedaled on that with the 64. But you might have had a different experience and are only remembering things like Mac OS or Amiga, or Windows, and maybe that has influenced your preference. 🤷‍♀️ To each their own, anyway.

This is beside the point, but it might help some people in the short term: I was able to switch my subscription plan without penalty and then cancel immediately without the cancellation fee. Maybe that still works.

go to bed at 2pm and get up at 10pm

While we are making reasonable demands, stop using 12 hour time. Sincerely, everyone else.

A bit underwhelming.
