Seems to me there are two polarised opinions here.
One from pilots who observe the published aircraft limitations and have no problems.
The other from people who think that limits are to be ignored when it suits them, suffer a fright as the consequence and then call it a design fault.
"Whaddya mean, stressed to 4G?
I've only been pulling 5G all morning and then the wing came off this afternoon!!
I think you're a crap designer!"
