I would not hold them responsible for what happened.
They are not beholden to their job.
If the captain is about run the ship aground, they should stay at their posts and go down with the ship?

And to say they have a responsibility to "Gun owners across America" is ridiculous.
It is a business like any other, a product is a product.
Does this analog work? If this was an auto repair business, would you never go back to your mechanic at his new shop?

I am not happy about what happened, I bought things from them and never had any issue.
In retrospect it would seem I may have lucked out.
I would not hesitate to to look up the new company and may just swing by to see them next time I am in the area.
