Sorry @san+1kwdENSV - your perception of wisdom differs from mine.
This DXC strategy is nothing new.
I retired some years ago, but prior to that was regularly asked to pass on knowledge and help train colleagues. I was happy to do this, when said colleages were part of my (global) team; once upon a time this used to be called succession planning.
However, when it came to being ordered to pass on detailed knowledge of a system solution we had built, to employees of a competitor (since DXC has lost a run and maintain contract to them), I drew the line.
This proved to me senior management have no concept of intellectual property, knowledge value, nor the innovation abilities of existing company employees. Add to this the ludicrous lack of salary increases year on year, and you have a clear explanation of where this company is heading.
The original OP is right to be cynical.
