I only know that there have been no reports of hardware changes since we reached KB12 and that was quite some time ago. So, for now, yes, it does seem to be about firmware. Though that doesn't rule out the possibility that they may find something important they can't fix in firmware and change the hardware. But it's just a possibility. Nothing said to make me think it will be the case.
But this isn't a matter of what may be "more" of an issue (assuming there are supply chain issues anyway). If someone could have pointed to Samsung's exploding batteries but found something else wrong that was even worse, the battery issue by itself would still be enough to require a full recall - or, preferably, a delay.
BTW, I did both a google search and duckduckgo search for what you said and there were not even a half dozen links, not all of which were even about WayTools and none which showed the issue you referred to.
Some time ago I looked at the BBB site and found just a couple complaints - hardly surprising since it hasn't shipped and people get frustrated. So I just checked again. There are only 6 comments (5 of which are complaints). Some of the complaints aren't accurate. The complaints that have merit are pretty much what we already know - they haven't achieved any of their shipping estimates, they don't communicate enough, and some people who complained had their orders canceled (while neglecting to point out that typically WT give a week for those people to reorder AND retain their place in line.
Nothing in there about supply chain issues either.
Since it hasn't shipped, it is really hard to have positive reviews so no surprise that almost all are negative. But their score of "F" is pretty meaningless in this situation. You need 60 points to go above an F. You can go below that with just a couple of complaints when there is no opportunity to add points.
This keyboard is heavily impacted by firmware. Far more than any other I've ever heard of. We've had this brought up many times, the typical expression being, "It's JUST a keyboard". No, it isn't that simple at all!
Don't agree with that at all. In any case, that is strictly WT decision. We have small amounts of money invested in it, which we have also always been able to get back. Far more risky for WT.
It is certain "a" risk. May not be the biggest.
Ah, yes. That is something we heard a lot back in 2015. In fact, we were told to expect some Chinese company to do a knockoff in short order. Yet here we are, (unfortunately) 3 years later and, surprise, no one has come close. I would almost expect they tried so maybe they found out it was a lot tougher than they thought too - and while they may have been able to copy hardware, the firmware - critical to the TB - proved too tough to invest in. Nor have I seen any reputable company offer anything that comes close.
