The ASX also only asked the ISX for things related to licences and invoices, and not activation codes. Software licences is NOT an activation code and is instead merely terms and conditions, agreements for usage.
This is the work that ISX did:
To use your analogy:
The PC shop should know what the name of the trading software is and its terms, agreements and conditions ie. the licence, for example, microsoft windows. You can not install a legitimate software without agreeing to its licence. Presumably ISX was the one who installed the software so they would have been the one to agree to the licence unless it was the customer who installed the software. In that case, why didn't the customer buy the software themselves?
The fact is that ISX themselves stated that:
So ISX MUST have possession of it at some point. Especially since they deployed the software and then use it for commercial use. How can you acquire something and then claim that you never had it?????????
Actually ISX was the one who deployed the licence!!!!!!!
