Actually he was pretty civil with you IMO.
From what he said in all the tweets, is that it's an Intel reference design board that is just used as is , or tweeked slightly by a number of tablet manufacturers. Probably they just buy the boards from the same place(s)
This is common practice and knowledge that Chinese manufacturers use Intel reference boards/designs in their products. Intel make (or have a company make) these boards/designs which they give out to be used or modified by tablet manufacturers.
Of course, if that KS prototype actually did use a reference(or variant) tablet board , then yes, saying in the KS campaign page that it used clickarm is wrong. Unless Rhomb.io had once sold a product that used the board and called it ClickArm. I notice they call a lot of their products ClickARM . That said, I cannot see on there site any such board that matches the board in question - so unless they had sold it previously and removed it from their site, then yes, it looks like the Smach Z prototype/PoC does not use ClickArm .
