Everyone seems to be directing their hate at Fluke, which was not at all related in this. People seem to believe that Fluke sued/did something to cause this specific shipment to be seized, when this doesn't seem to be the case.

They applied for a trademark on this, and got it. Now CBP is enforcing the trademark. CBP certainly doesn't ask Fluke before seizing a shipment. The issue here should be the trademark process, not Fluke.
