At least they eventually replaced the "Gen Y" placeholder with an actual name...
You know that word that Gen X hates, because the media constantly uses it to refer to us? Yeah, neither do I.
Just be glad that your generational cohort is large enough that people will actually pay attention to you as an advertising demographic or voting bloc. Even when the Boomer-controlled media is ridiculing you as special snowflakes in your safe spaces, at least they're talking about you.
I am also in the target demographic, and agree that it doesn't appeal to me. I would imagine that it would appeal to others our age. Most people I know aren't like you (presumably) and I, but I try hard to meet people with different interests and I could see some/many liking the simple message.
