I honestly don't think he really had any opsec apart from those few applications, look at what tools he was using, what a joke. Fake calculator app to store files are great to protect from your parents, not the FBI.

He was clearly using Android and I bet he was using the stock rom, kyc sim card, and not even a vpn behind tor.

Don’t get me wrong, I’m very happy and relieved he was caught, but if he had done serious research and did a better opsec, it wouldn’t have been so easy for the authorities to get him
