From my point of view, not remotely insecure, just sick of fly-by-night companies with unsustainable businesses who end up with a load of people losing their jobs and all the upheaval & uncertainty that brings.
The last 20yrs particularly have been littered with airlines like these, and the cycle just goes on and on.
Sadly the industry is full of pilots who’ve had the misfortune of bouncing from one bankrupt carrier to the next. It’s depressing to see it likely happening again.
