I also believe there is no such thing as not having an Facebook or Google account. They create it for you by creating your tracked profile. The only thing that happens when you create an account is that they can give the profile a name.
Snapchat would've been very cute in the '90s before people had e.g. cameras on their phones, and when phone screens were lower quality (although it'd be problematic to make a picture in the first place then). Nowadays, its painfully obvious how irrelevant the service is.
The only relevance Snapchat has is their userbase, mainly consisting of youth; personal data, the databank as a whole (pretty much the same but worth mentioning), and the potential to start a new service under the Snapchat flag.
