So as someone who also is lumped into that category, I think it is intentional that the "Generation" they have created and are hyping is so large as to cover at least three discreet cultural groupings of people ( 80 to very early 90's, 90's to dot-com bubble, post twin towers ). However each of those groups who's cultural upbringing and psyche will vary greatly don't make a compelling group to market to, so they have taken the least common denominator of all three groups and lumped everyone into that so they have something they can sell to.

People who are one generation down also look at individuals who talk like this with distain, but all of us have a small portion of people our age who do participate in this kind of behavior and even though its a minority its a plurality so thats what gets marketed.
