No, the 'not illegal' reference is to clipeata only. Clipeata is not protected, which is a great shame, but it wouldn't make much difference anyway. All Neps in Kinabalu National Park are, you need a permit to collect seed there. Edwardsiana is in a special category because not only are you not allowed to collect seed without a permit, you can't even enter the part of the park it grows in without a permit.
As for well-known people being reliable sources, I know of one well-known Nepenthes nurseryman who dug up protected Nepenthes species in the wild, so there's plenty of dodgy stuff in cultivation, and hybrids made from illegally collected plants. It's not just Neps, the damage that orchid collectors have done over the years is legendary. Where ever there are collectors, there will be illegal trade.
As for jacquelineae etc, as far as I know, they don't grow in National Parks, so collection only requires a general seed-collection permit. In Indonesia, the collection of Nepenthes seed anywhere is illegal without a permit. Malaysia, The Philippines, Thailand and PNG don't have prohibitions that I'm aware of, other than in National Parks.
