Said no to downgrading - am I about to get served sneezers onboard?

On ICN-EWR where the boarding was delayed by an hour since they had issues with crew rest area so wanted to downgrade 4 people from Polaris to PP in exchange for $2,500 travel credit. I said no, and asked them to go further down their list of people (this was more of a last resort, and I know they could always just involuntarily downgrade me)
