Can't say I blame them though. Paul and Robin are two people. Sparkfun (and Adafruit) are massive by comparison and have big stores that sell the same sort of stuff in much higher volume. The Teensys are popular. Sparkfun does (or at least used to do) board assembly in-house. It seems like a perfect match on paper.

Paul and Robin were awesome to work with and it was disappointing to see them stop handling their own distribution, but I totally understand the desire to move away from even just the mental overhead involved.
