It’s not the same thing so I’m not sure why you’re taking umbrage with commonly use and understood vocabulary. Being fired means there was a fault on the employees’ part, which isn’t true.

I feel like we’re maybe getting confused about terminology here? “Redundancy” is a specific term for a specific form of dismissal. It’s not a euphemism for “firing” because firing someone is a different kind of dismissal. Terms like rightsizing, reset, re-allocating resources, trimming the fat – these are certainly euphemisms for redundancy that should be called out.
