The answer to the question if these products are open source, the answer is: no.

Here is my blog post from more than 2 years ago regarding the status of the Arduino Yùn:

And here is my clarification request on the Arduino forum, which is still unanswered:

I would be interesting to know if this is due to their Kramer-vs-Kramer situation or it is simply their new policy.

I would say that the Betteridge's law of headlines has been proven once again by this thread, but this is no article and the headline here seems more click-baity than the actual subject line of the thread.

The answer to your parent comment's question is "no", but their question was the inverse of the post's title.

So, this actually is an exception to Betteridge's law; the answer to the question is "yes, arduino is no longer open source".
