[...] WHO on the forums actually does release their miner with conditions and prices that are clearly disclosed in advance? [...]
I did, not so long ago. Works out pretty well as far as I can tell, but would likely get very messy if said miner was being sold to a large number of people. I don't know of any other examples, but I'd imagine other people have done the same.
Side note 1: Being public about the terms of the deal, and changing them after-the-fact, is utter bullshit. I'd say that's much worse than not being public about the terms but sticking to them no matter what.
Side note 2: I understand people are around here with a miner's mindset, and ROI is king. But, if you folks care for the potential of cryptocurrencies at all, maybe someday, try to pick some altcoin that you like, mine it even at a loss, grow a bag, help that community, participate, develop some service, some utility. Much more fun, and oddly enough, big profits on occasion...
