Respond "that quick"? Flux has been around for years on all major operating systems. It's even been around for years on the iPhone, and is commonly cited as one of the main reasons that people jailbreak.
It's not really the case that they attempted to evade the distribution system and then play the victim card. They've had no illusions that it would likely remain exclusive to the jailbreak community due to the nature of the platform and Apple's rules.
When Apple surprised everyone by saying they would allow sideloading in Xcode 7/iOS 8, f.lux thought great, we'll post it so non-jailbreakers can have it as well. Apple asked them to remove the sideloading variant shortly after, not because it uses private APIs, but because they were not distributing the source. It's always remained available to jailbroken devices (see https://justgetflux.com/cydia/).
