It's a fair point in principle, but it doesn't help the user.

If not having the word "manager" in your title turns out to be a big reason - and that might be the case - that other colleagues don't feel the need to heed our advice, and by not heeding our advice that is actually the reason for the product failing and everybody losing their jobs, then it's a pretty fair complaint to make.

For context, at both my current job and my previous job, I did an audit of failing products and found out that not only were the products failing that had not made proper use of research support (e.g. Product Marketing Managers deciding to do their own research rather than request assistance from UX), but in each and every case, the reason for that product failure was bad UX.

In other words, they ignored us and the product tanked.

It was just a lot less easy to ignore us when we had the word "manager" in our job titles, so it happened less often.
