Yeah, I always take snarky lists like this as an attempt to be hip or edgy, it fails both attempts here and just makes me think the developer, or whoever came up with that copy, an idiot. One thing is certain, they're not in possession of any ability in the comedy realm.
Probably not, I am a tech aware, young adult with lots of disposable income and nowhere to spend it. I can see how they would prefer to target the teenage set. Though I guess that isn't their target either as they say "you are at your parents house", which would be sort of tautological if their target were teens. So maybe it is middle aged folks? Retirees?
Here is another possible explanation: they aren't some kind of master marketers who unfailingly target their niches and never fail in such attempts.
Why upset them at all? It's not like the target users who would enjoy this sort of snark are ever going to see the message. Seems like a zero sum game to me.
