Homo.....that being so....why then have there been aircraft destroyed on the ground while crew members were doing the preflight checks on the O2 systems? I am familiar with several.
Oxygen does not burn....but it sure provides for a hotter, more intense fire should there be an Oxygen enriched atmosphere....as you well know.
There are multiple ways of experiencing a fire in flight but if the report of a cabin fire is correct then it rules out many possible scenario's don't you think?
The 350 amongst its many issues....does seem to wind up in a heap of ashes more often than not.
