I think what you said is exactly why people have different opinions on this topic: what counts as "gross negligence" and what doesn't? Different people draw lines at different places.
There's, to me, no obvious clear cut line. But here are some indicators that make me consider someone was being grossly negligent and/or even malicious:
- ignoring warnings
- acting against known-to-them best practices
- repeating a previous mistake
But, again, these are just indicators, not a checklist.
Interestingly, any of these can happen also due to stress, burnout and generally broken company/team culture. Including something like a CYA culture where if they don't do something fast, they will be blamed for it, and thus they need to move fast and break things.
