100% none of those people have permits for them... It's nearly impossible for pet hobbyists to get the permits needed to keep exotic beetles, and that's just a fact. However the USDA has been very lax in enforcing the laws regarding keeping exotic scarabs for the last decade, and so for the past few years exotics have been smuggled into the US and are being kept illegally on a an increasingly larger and larger scale. Without more funding it'd be extremely difficult or impossible for the USDA/APHIS to actually do anything about it now, so they seem to be just letting it slide for the time being and focusing on more high concern, agriculture damaging invert groups.
California has a weird legal loophole where you can keep exotic stag beetles legally, and Goliathus are legalized in the US, but that's about it for exotics here. Unless you work at a museum, for a university, etc., you can't get the permits needed to legally keep most exotic beetles.
