By his own admission, Matt Leaman / AmigaKit indeed did "help get the project back on track", as more than just the primary X1000 distributor but not yet an A-Eon shareholder and/or director, when Hermans left A-Eon CVBA in a mess. But this happened already in December 2010, so more than a year before the "account hack" incident.

The problem of your explanation is that it contradicts the known timeline.
