Ok but currently they are using IPFS so does it matter if they once used the cloud? Go here[1] and scroll down to tokenURI and input 1 and you will get an IPFS hash back.

I don't think the fact they are now using IPFS makes it any more credible either; IPFS is not a new thing and the valuations were huge already by September. They should have done it from the start. Furthermore that they can mess around with the base URL is not cool.
