Not at all, man. It's a good question. Not centralizing for the network in the short-term. But if only a handful of companies (or fewer) build miners and their software, it creates a weakness. Supporting open source mining helps prevent that. So yes, for your money a used S9 will provide a better short term return. But there may be longer term impacts if everyone goes that way.
