It is a product. It is something people will buy. Lots of people just don't care about privacy that much, and the privacy risk factors with this are potentially lower than for other things people use with roughly the same level of "realness".
More to the point, lots of people don't give a damn whether the people they are talking to care about privacy, and/or feel that it's somehow their place to make risk decisions on behalf of others.
Garbage people are a large and lucrative addressable market.
