Not quite a device manufacturer, but a technology company: Qwest CEO Joseph Nacchio was convicted of insider trading after allegedly refusing to help the NSA: https://en.wikipedia.org/wiki/Joseph_Nacchio
It may be a coincidence that he happened to both refuse to help the NSA as well as commit a crime, but "insider trading" as an officer of a company is pretty hazy, especially if you have the NSA informing you that they're going to tank your company's stock if you don't comply.
