I am not sure they are interested in the blockchain all that much, I was listening to the interview with their founder and their project is focused on the product, blockchain just happens to be an easier method to distribute tokens, so I don't think its really about the whole chain hype.
Will they have their token on other chains? I think that's very possible, but they are sending their tokens via uphold to get around that for now and with ETH's new hard fork, I think they may not need it too much, its not the core of their business
