my bet is that they are receiving so much submissions, and actually buying all of them, that I guess the company, or a few clever individuals, saw the "consulting" or equipment renting/financing potential and will try to monetize on selling cookie cutter packages.
Cameras like the Sony A7s or the Panasonic GH5 are great for the low budget film, but if Netflix green lights your project, you can afford much better cameras. Unless the project calls for really small and unobtrusive cameras, in which case Netflix would most likely approve the use of whatever camera best fits the project.
If you are not filming in a place where equipment rental is free like the US, GH5's become very inviting as your second (and third) camera.
Not really, at that level everyone in Hollywood is renting their cameras anyway. Indeed, one of them cameras on that list (the Panavision DXL) is only available to rent, you can't buy it.
