I live in Boise, and work at a software startup.

I personally do not think this will have much of an effect on the "startup scene" because the vast majority of the people working at companies that would possibly enforce non-competes such as Micron or HP do not come to work at "startups", because of performance on skills-tests or cultural fit.

I've met a lot of the leadership for various startups in the Treasure Valley, and suing someone over changing employers would be the antithesis of the values they hold, there is one exception I could think of - BlackBox VR (very early stage) somebody leaving them for a competitor could be pretty bad!

I have met startups brag about losing employees to Amazon and Google though.
