It can also become unstable with too much negative feedback.
But it has to be way overdone to get it unstable.

It trades gain (as you have written) for better linearity and less 
distortion, as all amplifying stages are not really linear

It is, but to say that positive feedback stabilises the amp is even less of 
an answer, it gets quickly to the point where the amp starts oscillating.
In any given amp you will likely find both forms
