Someone could start another one, or reach out to Tethrd to see if they're up for a Q/A.
It's a tough situation. The sticks appear well-designed, with "redundant" safety features (i.e. the pin saving butts when the glue breaks), a design that enforces favorable loading orientation on fasteners, etc. The stacking pin issue is super minor and understandable - maybe should have been handled somewhat differently (i.d. make the change before shipping, and for sticks in customers' hands offer to rework and resend, or store credit toward other stuff if you're doing their manufacturing work for them.
Another well-known vendor handled manufacturing issues with a cutting-edge climbing product similar to this, and they've had my business (and wholehearted public recommendations) whenever possible since.
The glue is a much tougher issue - it was clearly and unambiguously marketed as the structural support of these sticks, and we're seeing it fail. In my opinion, you really kinda need to recall in that case. If they'd marketed the sticks with the pin as the structural support and the glue for silence and solidity it would be a different matter (if still disappointing).
As an alternative a compelling safety argument could be made, with multiple tests on video (to failure) of glueless sticks, again along with some refund or store credit for accepting substandard sticks. And probably some changes made moving forward - whether a revised glue process or some other improvement ( say 2 roll pins!) to justify the price.
These are not necessarily easy choices to make, but they are important ones.
