I think they're just inherently very interesting. It's the typical Chinese bootleggers's approach to branding and design, just sticking a bunch of shit on the product (and not necessarily shit which is related or makes sense), because the typical customer will only just kind of recognize it as some large foreign brand, or at least that's the plan.
In the west, we find these bootlegs very entertaining for how bizarre they get, and thanks to McCollum a public light has been shed on the fact that the Chinese have been doing this with firearms as well. Given the high standards which are expected from consumer and military grade firearms in the west, and how you just don't see crude shit like this in anything from any kind of production line or factory (since we don't put up with shit like a lot of non-parallel lines, or sights which don't work), these guns are kind of shocking. You see crude guns from other places in the world as well, but often they bear little if any branding.
There's a lot of people who could be looked at as 'prepper posers' in that they claim to be prepping, but then if you ask them what they have actually prepared (as in, supplies, or if they even have any plans), they come with pitiful answers. The kind of person who thinks they're prepared for the end of the world because they've got a gun and some canned goods, and don't have any equipment or plans for sourcing potable water in an emergency.
