As you say, pure fbw, with no mechanical backup.and the a/c cannot fly at all without the electronics. .It's surprising therefore that there is no fire suppressant around the avionics systems. Assuming an electrical short taking out power supplies, even redundant systems could fail, or in the case of serious fire, the various systems could fail one by one over time as the heat reaches them. I know the acars is fragmentary evidence, but whatever happened seems to have happened over just a few minutes, which would need a fairly aggressive fire to heat all those systems to non operational state, because of the thermal mass involved...
