Yes, albeit with more grammatically mature postings.
You say it as if it were a bad thing... while assuming that such people were immature at that point anyway... But here's the rub: No matter how 'mature' a 30/40/50-year old might like to think they are, the instant they walk into one of the Expos I work at, and they clap eyes on a Lightsabre or a Pulse Rifle or a Proton Pack or a KITT car or a BTTF DeLorean or the General Lee or any of the other iconic props and costumes from their favoured films and TV shows.... They go all giddy and start acting like teenagers again!
My own wall decorations included the very motorcycle I now own, and several of the sports and muscle cars I've worked on for their owners.
If that makes me emotionally and stylistically immature, so be it - I'm clearly having more fun than those of you who think your perception of maturity somehow makes you better, or perhaps even somehow qualified to dictate what people should and should not like... rather than taking the more mature approach of just accepting that some people like different things and getting on with finding options that suit your mere preferences.
But given that those very people are the ones now designing what you presumably assume are the 'stylistically mature' products you seem to imply people must desire, their creative inspirations and dreams clearly served them well enough to make the stuff that you now endorse... so again, how is this a bad thing?
Moreover, they're also designing all this RGB stuff, which plenty of other people are happily buying and for which other manufacturers are providing connectivity, which strongly suggests that a lot of people do still want this, regardless of what you think they should.
