It seems a case of rushing a product 9-12 months ahead of schedule, scrapping two silicon revisions, as mentioned in the announcement[0] in their haste to be "production ready". "Good, low-cost USB-C power supplies (and USB-C cables) are surprisingly hard to find, as we discovered when sending out prototype units to alpha testers" In hindsight that reads that they tried a bunch of off-the-shelf cables and were perplexed about why some of them didn't work. So they built their own official power supply that worked around the design flaw.
