Offering up a loaf of bread pre-sliced isn't rocket science either, but someone has to have the idea first, and executed it in a way that other people say "Wow why didn't I think of that before." or "Huh, I could really find this useful."

At the very least Apple could offer acknowledgement.

Tweaking color temperature has been done in Hollywood since... well, color. You won't see a window on a set that hasn't been treated to balance indoor and outdoor light. Tinting flashbulbs is common. Film editors select different bulbs and gels in tiny cubicles during late night razor-and-tape editing sessions. When video got popular in the 70s, they nudged the tint control. Mid-80s Amiga video games shifted from day to night -- shadows too! TVs ship with day/night/game modes. 10 year old car navigation systems automatically switch colors at night. There's literally nothing new under the sun.

EDIT: yes, you can convert light to orange. http://www.hurlbutvisuals.com/blog/wp-content/uploads/2013/0...

My grandparents had a TV from the 1970s, possibly 1960s, that would automatically adjust the color balance to match the room lighting. It really is an old idea.

Shipped on LCD TVs from multiple manufacturers in 2008, too: "new TVs automatically tweak their on-screen colors to complement say, the orange glow of incandescent lights in the evening or the bluish tint of midday sunshine." Six months before F.lux shipped.

Then why was it impossible to do on iOS (iPhones and iPads) since 2007?

I find it alarming that so many folks are supporting the actions of a company to control and inhibit innovation, literally hurting consumers' health in the process, in order to control and maintain their forced 30% cut of third party program revenues.

They have literally implemented Palladium and Trusted Computing and it looks like people cannot get more of it.

No they haven't. There's no TPM in modern Apple computers of any brand. And there's certainly nothing like the NGSCB Nexus, which I'd think essential to calling something "literally Palladium."

There's a TPM-like mode with hardware isolation built into ARM for years, used for disk encryption keys, DRM, auth keys, fingerprints, etc on IOS and Android. See: https://en.wikipedia.org/wiki/Trusted_execution_environment

The secure enclave on iOS devices is basically a TPM. See https://www.apple.com/business/docs/iOS_Security_Guide.pdf

>Then why was it impossible to do on iOS (iPhones and iPads) since 2007?

Just because nobody had baked the feature in.

It was also impossible to have a screensaver on iOS, but this doesn't mean screensavers are a new thing.

True, and trying to sell a "bread slicing" service, as a separate product to selling bread, is very obviously going to fail as soon as bakers buy bread slicing equipment. f.lux are trying to sell bread slicing, not bread.

And open themselves up to a lawsuit? Nope. Just keep pretending like it's obvious. Even though we've had blue-tinted screens for decades and no one came up with a similar feature.

Backlit displays have only replaced CRTs in the last 10 or so years. I don't recall old monitors having a problem with being blue.

They had. In the 1990's I worked frequently into the night and owned a CRT with color profiles. After the sun went down, I switched to a more warm profile.
