React makes me sad because the PATENTS file means I can&#x27;t sell my creation to anyone suing Facebook for patent infringement.  Personally, I don&#x27;t think that software should be patentable, but it is and deep pocketed companies are always suing each other over this and other IP.  Even if they aren&#x27;t today, there is no guarantee that they won&#x27;t tomorrow.  So why bother with a technology that pisses in the proverbial pool, especially one full of lawyers (aka deal killers)?
