Had some spectacularly bad customer support experience with them. Watch stopped charging well within the warranty period and it was an absolute nightmare trying to get them to fix/replace it. Either systemic incompetence or a deliberate tactic to try to avoid making good on the warranty.
Whether or not they are US based entities I think is moot since several developers have already been booted from kernel development due to their affiliations largely at the behest of the US.
Also if they try prevent downloads it would have the interesting side affect that: all the folks out there seeding and torrenting Linux ISOs might have to now also claim they only share the un-embargoed ones, wink.
