What I would want to know is: were the removed pax revenue pax or non-revenue pax. There are thousands of people in Thailand: third cousins of ex-TG staff, retired politicians, police and military officers etc who have been given free flight benefits years ago, and who keep enjoying those benefits.
If a fare paying pax is bumped, something is wrong. If someone flying for free is bumped: not a problem.
Just my 2 baht...
