From what I recall, it was for both themselves as an organisation and to help JWs who'd suffered too. Both were within the terms of various holocaust compensation schemes. I'd question some of the things they suggest in that letter of application (asking to be considered as heirs for those who died without them, and the educational aspect I'd be concerned about given their exceptionally narrow focus), but they were banned, probably did suffer losses as an organisation which would entitle them to some compensation etc.
I just hope that their arrangements for survivors has never put inappropriate suggestions to those in receipt of compensation just for signposting them to it. There were complaints over the secrecy not permitting proper monitoring of what was happening.
(NB: note that the JWs didn't give a stuff if you'd suffered because of being a JW but were no longer one in the early 2000s....)
