Very few mediums are totally ad free, and Netflix is no exception. If a movie or TV show on Netflix (including their original stuff) has product placement, the product placement remains a part of the media and is not altered. That would be generally prohibitively expensive. I notice this especially with criminal investigation shows, where for some inexplicable reason the whole division is using iPads, or every monitor you see features a prominent Dell logo, etc etc.
Its worth pointing out that until recently, as I understand it, most forms of product placement were not allowed in the UK. As such, many american tv shows and movies literally had scenes cut out. Turns out, it rarely seemed to affect the content, but perhaps thats because anything important got another take without the overt product placement
