Have you all heard of this ?
http://makezine.com/2015/03/19/massimo-banzi-fighting-for-arduino/Apparently one of the originators (Gianluca Martino) of Arduino went and trademarked Arduino in Italy behind the back of the other 4 founders.
He has now cashed out and sold his company to a fortune hunter.
This guy (Federico Musto) has changed his company's name into Arduino S.R.L. , registered Arduino.org website and his team has forked the original Arduino IDE. Arduino SRL (the new 'Arduino') has sued Arduino LLC (the other 4 originators) to stop using the Arduino name. LLC has also countersued SRL.
So now we have two companies (Arduino SRL and Arduino LLC), two websites (Arduino.org and Arduino.cc), and two github repositories that have different Arduino IDE's available for download. Arduino SRL can make 'Arduino' brand boards in Italy, while Arduino LLC can only do so in the US.
It's gonna be one messy and expensive divorce.
