The dual input warning doesn't inform specifically that copilot 1 is pulling back on the stick. It's clear from the report that was the problem, copilot 1 was pulling back the whole time and nobody realised.

There is only 1 pilot at a time that is supposed to fly the plane, so the warning in itself indicates that they are in serious conflict and should clarify who is flying and what to do. They payed no attention to it. Again, hard to believe adding more audible warnings would improve that, rather than make it worse.

At some point they are discussing whether they are ascending or descending, while the stall alarm is blaring throughout. I don't think anyone will consider making the stall alarm go "Stall! Losing attitude!".

"Pull Up! Pull Up!" not "Ground!"

Notice how in this case they did get that warning...and it further doomed them, because Bonin started pulling back again.

"At some point they are discussing whether they are ascending or descending, while the stall alarm is blaring throughout. I don't think anyone will consider making the stall alarm go "Stall! Losing attitude!"."

Yep, but your missing the fact that they didn't believe it was actually stalled or about to stall. They thought that was impossible since normally the fly-by-wire protects against it, so that warning can safely be ignored. That is why they ignored it. It's kind of like the boy that cried wolf. Normally, the warning can be ignored and so when it started sounding when it really mattered, they ignored it. Maybe interlacing "Stall! Stall Protection Disengaged!" (when in alt mode) and "Stall! Push Stick Forward!" (when stick back) is the ideal solution.
