The biggest shameful fact is that the decisions who are fired were taken in many cases on the basis of personal relationships. Their senior most engineering person is "close" friend with very senior lady who has special "blessings" for a contractor company. That has impacted many and so much so that many capable permanent people are fired saving higher paid contractors . They both are pretty shameless about it in open and many old employees are aware of this.
Sooner or later Thoma people will find that ethical code violation and fix it but many more may get affected by then.
Hope one of the remaining ones can gather courage and report it soon.
