That’s a pretty interesting thought experiment. How likely is it to burn bridges with a multibillion dollar corp by taking them to court to protect your IP? They might even respect you for it. Most likely the people working there will move on eventually and especially if they are responsible for IP theft that results in a heavy legal bill. Companies sue each other over ip all the time and then still do business with each other. I’m also assuming OP’s bridges with the persons directly responsible are already burnt. So which bridges exactly are being protected?
