Oh that's not at all surprising that they tried to roll their own encryption. But if they are already not that sophisticated, then they'd still not be able to glean much value from these revelations. Surely someone rolling their own encryption doesn't understand the big deal with NSA's BULLRUN program (where they tried to weaken encryption algorithms by planting people in teams and attempted to weaken protocols, or target vulnerabilities in encryption libraries).
