Yes, yes I do, I've mentioned it many times, followed by encouraging you to follow through and do your own research.
KnC have not chosen to sell to businesses to defraud a forum and lull it's members into a false sense of security with any illusion of a promised refund. I'm pretty sure it has to do with the VAT complications pertaining to individual EU countries max allowance. Ask your CCard issuing bank if they have issues with you purchasing a product intent for business to business sale, and whether it negates any consumer protection they may have.
KNCMINER is shaving 1 year warranty off of your 2 years consumer warranty by using the "for business use" line.
That's an exclusion clause staring you right in the face but you can't be bugged to see or admit it and rather spread BS about KS (haha). That's a rather pathetic way of spending your time while you could, in effect, talk to a real lawyer and set things straight, at least for the UK.
You are right about your assumption that businesses have some consumer rights, as in they should get what they pay for and "it" should work satisfactorily. Sadly, you're mostly wrong about the rest but don't know enough to realize it and certainly don't have the experience in court to back up your own (mis)information.
You're a KNCMINER fanboy, good for you, you tell people to double check things, make up their own mind, not overspend, all good. But stop giving legal advice when you don't know the first thing about it.
