The incentives align to make me want to support f.lux here, I think. Not because I want f.lux (the product) to win, but because having Flux (the commercial organization) in the market means that they&#x27;ll &quot;hunger&quot; for that money and use it to push Apple to open the gamma API.<p>Having done so, though, anyone can then use that gamma API. If there&#x27;s no special advantage to f.lux&#x27;s patented implementation, then some other (maybe FOSS, maybe not) gamma-shifting app will win the market. If f.lux has especially clever secret sauce in how and when exactly they gamma-shift, then f.lux will win the market.<p>The real question: should someone be able to clone f.lux&#x27;s (latitude, time, and option-dependent) gamma curve formula without paying f.lux? Is a gamma curve formula patentable? I don&#x27;t really know. I <i>do</i> know that it&#x27;s easy enough to create your own that probably works <i>nearly</i> as well without it being f.lux&#x27;s formula.
