His company won - they violated the NDA and misappropriated trade secrets, why would that lawsuit have been frivolous?

You are right, that was unwarranted. I just have an instant knee-jerk reaction when I see people with multiple lawsuits.

You should look into that.

What about this is frivolous? Maybe he's just more willing to stick his neck out than others are. We need more people willing to do this and less fawning over tech companies.

Totally agree! I have found very few individuals will speak up, or do anything when their career, or money is involved. Oh sure they will speak online, but actually calling out a superior, or questioning a professor in school; they shrink into their seats. I haven't figured out if they are scared, or just in denal. I often wonder if I would have been one of those people who administered the high voltage in the Milgram experiment, but I don't lose sleep over it because I walked away from too many jobs, and ripped apart a Professor or two. That said--I'm not successful and have a spotty work history.
