I don't know why anyone would even call this a "debate". No one's advocating using etherless fuel for regular sport flying, or claims it's better than ether-containing fuel. Just pointing out that engines CAN be made to run on etherless fuel doesn't amount to debate, and in any case it's pretty obvious it can be done, so there's no actual thing to debate anyhow. There are potential uses for such engines which aren't necessarily those RC hobbyists would be interested in.
