And now we get to my question of why. They want the Linux source code, the company is not giving it to them, why is the next step a blog post instead of a lawsuit? Again this is a medical device - it's important enough to spend the money on.

They make a blog post about GPL violations which allege the company is violating the law.

I'm absolutely begging for anyone in a similar situation to prove it. The reasons those emails were sent is because they think they have a legal entitlement to be sent the source code. *PROVE IT*. It's cheap!
