From the f.lux EULA, which I&#x27;m fairly certain no one has ever read through (evidently, because there hasn&#x27;t been a backlash over it):<p><pre><code>  You may not (and agree not to, and not authorize or enable others to), directly or indirectly: 
  (a) copy, distribute, redistribute, rent, lease, mirror, timeshare, operate a service bureau, or otherwise use for the benefit of a third party, the Software; 
  (b) disassemble, decompile, attempt to discover the source code or structure, sequence and organization of, or otherwise reverse engineer, the Software (except to the extent applicable law prohibits restrictions on reverse engineering); 
  (c) remove any proprietary notices from the Software; or 
  (d) bundle the Software with any third party software, product or service. 
  You understand that Company may modify or discontinue offering the Software at any time. 
  For the avoidance of doubt, the foregoing restrictions apply to any company or corporate entity (or its affiliates or agents acting on its behalf) (each, an “Entity”) and 
  no Entity shall download or install the Software for the purposes of mirroring or distributing it to its employees or otherwise.

They also write at the bottom of their homepage that &quot;f.lux is patent pending.&quot; Next to an offer of collaboration with cell phone, display, and lighting system manufacturers. Which is code for &quot;We want money for this.&quot;<p>Why do people support this software? Especially on HN, which should know better. This is the kind of software that wants to be free, and could be made better through open source.<p>If you think this is ridiculous (as I do), Redshift[1] is a free, open-source alternative for at least Linux. On Android, ChainFire&#x27;s CF.lumen[2] at least does not make a patent claim on filtering your display, and allows you to use &quot;Pro Mode&quot; without paying (you simply have to enable &quot;Freeloading&quot; from the main menu).<p>1: <a href="http:&#x2F;&#x2F;jonls.dk&#x2F;redshift&#x2F;" rel="nofollow">http:&#x2F;&#x2F;jonls.dk&#x2F;redshift&#x2F;</a><p>2: <a href="https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=eu.chainfire.lumen" rel="nofollow">https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=eu.chainfire.l...</a>
