Here's the mentioned section of Ask An Engineer:
I think that requires a bit of context. The guy in the video, Phillip Torrone, has been on a bit of a crusade regarding the licensing of the arduino.org boards some time before the announcement of the Intel Curie end-of-life. I definitely support him in trying to get answers about whether products advertised as open source hardware are actually open source but I feel like he's really reaching to shoehorn this Intel thing into it with zero supporting evidence.
They talk about the Arduino 101 being discontinued but it goes beyond that, it's the end of life of the Curie module entirely. You also have see this in the context of the recent discontinuation of the Edison, Galileo, and Joule. Surely there would have to be an easier and cheaper way for Intel to distance themselves from Arduino than dumping all the investment they've put into those products. Remember the Joule was never even used on an Arduino.
I think that Intel had no idea how to be successful in the maker market because they have never done anything like this before and didn't take the time to understand how it works. I'm guessing they underestimated the required investment in support software and documentation. They overestimated the amount of community contributions and the amount of administration that would be required to handle those contributions. They overestimated the sales volume. It's a common mistake that people new to the market think they can just slap some chips on a board and cash checks. There are plenty of dev boards out there already, what we want is something that is well supported and documented. If you can get the ball rolling then the community will keep it going but it takes that initial push and that's where Intel failed. It's likely that the chaos of the Arduino vs. Arduino thing hurt their sales volume to some extent. I don't know what level of involvement Arduino was supposed to play in producing the support software and documentation and whether they met their obligations. So it is reasonable to think that Arduino might have been a factor in the failure of the Curie module but it's far from obvious to think that the revelations of Musto's faked credentials and the licensing question was the sole cause. Maybe the latest drama was the final straw but it's also possible that Intel never even heard about it.
