I think the case is still developping, but I hate these laws that forbid employees from working at other companies. I thate to take Apple's side, but I don't think hiring the engineers was wrong.
Like you accummulate knowledge at your current company, and you're not supposed to use it ever in any job? Bullshit. Masimo could have offered their knowlesge employees better salaries stock options so they stay, at the end of this case if Masimo wins, it's the employees that will lose.
Anyone working in a specialized field will find it hard to be hired as new companies will be afraid of the same thing here.
