Would Bitcoin have grown as much as it has if everyone still used massive GPU farms, sucking down electricity like the proverbial? Lower costs of mining mean fewer coins need to be dumped to pay for it, which is a good thing.
If a coin's "growth" (which in Bitcoin's case I don't attribute to ASICs having replaced GPUs, by the way) comes at the cost of massive centralization of that coin's production, it's by no means a good thing and completely against the basic principles of DigiByte.
