These are exactly the reasons I just bought an Avalon 6 and not an S7, despite the S7 being just slightly more efficient.  I told myself I would never buy new asic gear, I started with a $20 S1, then graduated to a $100 S3+, both before I even really knew who Bitmain was.  I recently picked up an S5 for <$180, another good deal for the hardware, but buying used I didn't feel like I was directly supporting Bitmain.  I will run the S5 for a while still, I may bring the S3+ back but yea, it is tough to completely separate from Bitmain since they are so pervasive.  Once I saw how Avalon supports cgminer I made up my mind that they would get my money if/when I decided to buy a new, current generation miner, and they did.


It's unfortunate that the bottom line has to drive business decisions many times.  Even though the Avalon 6 is not as cost efficient as the S7 if it were my business I would do everything I could to put my money with Avalon; sometimes making the "right" decision is better than making the cheaper decision if your business model can support it.


You are a paying customer, you have a service with them, you are entitled to use that service as long as you pay for it.  You should have brought a lawyer, not an electrician.  They don't get to tell you what you can or can't do on your property, nor can they limit you to an arbitrary average value of those residents around you.  They are stupid to drive away a well paying customer.
