If you deploy the same identical content onto multiple platforms, you will have a duplicate content issue going on to some degree.

I'm sure that 98 percent of the people that would employ this service have no idea or do not care what duplicate content is.

Just makes it easier to develop new readers IMO. More places your blog lands, more chance of people picking up on it. It's like syndication for 14 year old girls.
