Cheap rv/camper outlet on amazon… neutral all tied together

Amazon would likely go out of business if they pulled everything that was required to be NRTL listed, but isn't. Tonnes and Tonnes of their lighting fixtures aren't listed.
Amazon, Wayfair, Temu, possibly some even can be found at big box stores, though majority of them I've seen have some listing but make you wonder if valid or how they ever got a listing.

One the worst ones I've seen in a few different variations lately has been vanity mirrors with back/perimeter lighting incorporated into them or towel warming racks.
