In the end it looks like both groups came out ahead and nothing with the "system" changed. "Same as it ever was."
Actually, sparkfun lost. Should they ever get caught again importing a few thousand yellow/gray meters they no longer have the excuse of "but we didn't know", and Fluke is unlikely to bail them out again.
Fluke won. At the cost of some small change for them they got their message across. Not only to sparkfun, but to other importers, too, who happened to read the story.
And why should a low-profile, small change, single event change a system that is a few thousand years old? Controlling imports and exports, charging customs or denying the import of unwanted goods aren't exactly new inventions.
