Probably you were down-voted because of you starting with "What you are saying is wrong." People probably didn't like your tone and the original comment was only somewhat inaccurate. There still are more features in f.lux than the built in options.

And I assume you understand that since you edited that line out.

Correct. I realized that opening line set the wrong tone and was unnecessary.

I know these features exist in some places. But nobody had it before f.lux. And it's still - imo - one of the best implementations.

f.lux screwed up how my MBP displayed graphics so I'm just using the built-in tool now. Unfortunate.

IIRC that's a bug in the Intel graphics driver or something. I ran into that in the past as well and it's not directly f.lux's fault.

There was nothing wrong with your tone.

Night Shift on iOS and macOS also has a sunset-to-sunrise setting.

You'll almost certainly get down-voted on HN for whining about being down-voted, and for comparing it to Reddit.

Just checked. Also Mac OSX has Sunset to Sunrise based on location.
