I am not @purism staff, just someone who managed to buy a couple of Librem 5 units second hand. Still waiting for my original orders to ship, for both Librem 5 and MNT reform.
The situation is similar in both cases, perhaps for similar reasons. They are selling a new thing without knowing how long it will take to deliver, giving optimistic estimates of when it will ship.
I can understand why they do it, but I think both underestimate the trust problem they get.
