So, because you disagree that LinkedIn will pursue expensive litigation for no real benefit to them, you're dismissing everything? You're saying the OP should be afraid? Should spend a fortune on attorneys? Should not declare bankruptcy upon loss? I respect that you disagree. I do not respect your focus on a minor detail to dismiss everything.
A portion of your comment was aligned with my own view, sure, but I read the substance of your comment to be regarding the likelihood of LinkedIn following through on their threat and the correct course of action for the OP if that happens.
The OP should absolutely be very afraid because they’re posing a threat to LinkedIn’s hundreds of millions of dollars in revenue from a very vulnerable position. Bankruptcy is brutal and expensive, the OP’s focus should be on avoiding litigation no matter what: telling LinkedIn to suck it is not an option, and bankruptcy is not the “oops hehe bad roll I’ll try again” option you portray it to be.
