Your first point: this would obviously be serious fraud. I'm not sure if you have any evidence of this in this particular case or is you are alleging this is standard practice by PE funds?
Your second point: why would someone lend money to a company which was going to go bankrupt? If PE firms always made the companies they controlled bankrupt, no one would lend to them.
Your third point: if someone buys a company from you, how does it make you a creditor of the bought company?
