The same argument could be applied to nearly any product. Knowing how to use the product is the user's responsibility and helping educate users is the manufacturer's responsibility. If you don't have data back ups, regardless of the type of computer, then you're setting yourself up for disappointment.
True, maybe I overreacted. What worries me is that is apparently supposed to be sold as a general computing device. Tamper-resistant hardware may be used in the military to protect implementations and keys stored in hardware that will eventually get stolen. For other types of data stored? Probably not so much. As I said, reasonable uses for this kind of device are limited.
For ordinary users, deleting everything immediately when someone tampers with it is a recipe for disaster. Sure, they can backup everything in encrypted form, but then the data is not really deleted when somebody tampers with the machine, isn't it?
Regarding the security, well, apart from software-based attacks, how about installing a tiny USB keylogger inside a USB cable that is already used by the user? Or in the keyboard itself? Or a camera that records your keystrokes?
That's what the <insert agency or special interest group of your choice> would be doing in such a case.

Not all products are the same. It's irresponsible, but maybe good business strategy, to presume a complicated computer, which runs software that no human can hold in their head is the same as other products people are accustomed to.
Let me state a section of our product description here, detailing the way we are approaching the "Evil Maids"
USB volume boot blocked at BIOS,
BIOS access controlled by security key + PIN,
Intel TPM is enabled, and we do not enter a passphrase to unlock encryption (unlike software based full disk encryption)
In addition, attacks that don’t rely on booting to a USB device are protected by powering off the USB interface when the user keyfob is out of range

The comparison table ( https://www.crowdsupply.com/krtkl/snickerdoodle#comparison-t... ) includes a bunch of common, but under powered platforms (Arduino, RPi, BBB). It should really be compared against higher-powered FPGA-based platforms like the Numato Opsis.
There are quiet versions of Matias switches, but they are all clicky, which we explicitly don't want because even quiet clicky switches are loud and because of the associated fatigue. Our switch is quiet and non-clicky, which up until now hasn't existed in the Matias line.
I'm not sure I understand your question about wanting money. As much as it would be great to give them away for free, the reality is that it cost us money to produce them and it will cost us money to ship them. We're running this campaign in order to simplify the logistics of offering our extra keys to other people.
Regarding custom key caps, another commentator was correct in saying that we're milling entirely custom shapes from raw materials (aluminum in our case).
As for the circulation of Cherry MX Reds, I could only find them available in small quantities for what seemed to be very high prices, when I could find them in stock at all. The Cherry MX is a great line of switches, but Cherry is doing a poor job of helping people (well, me at least) make new products.
I haven't noticed the Matias switches being super wobbly, but I also don't have a full keyboard built yet. I'll keep an eye out for this.
