There have been some interesting technical developments with regard to the points Jay is making. For one, FCC certification should only be necessary for the baseboard -- the SOM and PCIe devices should carry their own certification. The fact that they are supposedly sending these out without certs for the baseboard is hugely concerning -- and illegal. If anything, this is the core reason why nothing has left their hands yet.
What else is concerning is that they are shipping the SOM without schematics or documentation -- even the dev units have no details on their construction. For reference, Purism only made the baseboard and mechanicals -- the actual SOC and RAM are on a module made by Elecom. I asked about this in their matrix channels and the best answer I could get was "it will be made open" -- a tall order, given the past history of Elecom keeping their designs close to their chest. This is most likely the core reason why their thermal and RAM performance sucks -- the community can't get in there to help.
Note that they aren't even running the RAM at full speed -- that's not something you can easily change without re-generating the training programs, and locking that in without proper burn-in or huge amounts of QA to validate is going to likely be the biggest hurdle they will face. Especially given the requirement that the program not be updated.
Source: built and shipped SOMs using the i.MX8MQ in the past and still supporting them now: RAM training is a huge problem.
