I'd be ok with this and other lies having legal (civil) consequences, i.e. CEOs who say this are personally liable. Obviously, this phrase would die and that's the point.

Really, it's not hard to remain authentic. Statements like "I feel terrible" are fine and even "we're trying to support everyone through this transition, both staff directly affected and their families, as well as the remaining staff who we realize shoulder increased burden." Without saying "we're doing everything we can" and other obvious lies.

“I take full responsibility” means “I am not firing these people because of their faults, I am firing them because I need to and had I better foresight, I wouldn’t have hired them in the first place”

The firing is a necessary consequence of the hiring. You can, if you want, make it harder to fire people — but if you do you will also find companies will be less willing to hire people.

Perhaps that's what the speaker intends but not what affected listeners are likely to hear. In the west, it's the speaker's responsibility to make themselves understood by the majority of listeners.
