The employees who advocated 'freely giving' the technology away jumped off to the other company basically right away. It was sabotage by unethical employees.
If that's unclear to you, you're probably going to have problems on the ethics exam.
Who signed off on the decision to give the tech away? Anyone can advocate for anything, at the end of the day someone is in charge and the questionable business move is on them.
you're right someone made that decision but on the advice of a lot of experts who sabotaged the company, advocated to giving the tech away to another company, and then left to that company.
This isn't rocket surgery - it's not complicated. You're just trying to minimize unethical actions by a group of people who sabotaged their employer.
If the picture is as you paint it, seems like Valve would want to pursue legal action, as Google did when Anthony Levandowski jumped ship to Uber with Waymo secrets.
Valves flat structure creates a very different organizational response than Google. And these aren't "jumping with secrets" which is a different situation.
But ethically, oculus is bankrupt.
