They do not have an answer to this question only their personal thoughts on this matter. They bring up that the self-distruct is a chemical process and should therefore not be stopped by an EMP. It is also a concious choice to destroy your own ship, and they think that in the future that when there is a higher cost to dying and losing your ship people will not use it as an easy way to avoid pirates.
