As asked in the title. Anyone have insider information? Speculations are welcomed. It just seems such an e-waste, but at the same time some reviewing more well known techs are helpful. But those whose goal is to make their video entertaining rather than informative like going on a tech shopping spree on Amazon or Aliexpress to show the "smallest" gadget in a certain category or something similar is adding to the waste.
Depends, a really big tech reviewer probably gifts some stuff to his friends and family - other than that they all have a huge amount of physical storage. Like others pointed out, big companies like Linus Tech Tips have a huge Warehouse.
