You don’t have to dig commodore from the grave, there are current-day examples of companies doing the same.
Just to name one (even if it’s not American): Canonical.
It (canonical) is registered in the isle of Man, a fairly known tax haven.
Also pretty much every company with a "headquarters" of some kind in Ireland, notoriously including Apple.
