Lol? How does a 12-15 month ROI make Bitmain evil (or even greedy)? Any other investment opportunity with those types of quick returns would be killed for. Most people who like cryptocurrencies also like the idea of a free market - in which price is dictated by supply and demand. I would argue that Bitmain has been seriously underpricing their products for years or else there wouldn't be such a vibrant resale market and they wouldn't sell out so fast. Sounds like the opposite of evil to me. Perhaps we are the ones who are being greedy by seeking to enrich ourselves faster. There sure are a lot of rocks getting thrown in this glass house
