I think the official forums is not representative of the overall community, most of us here have been playing the sims since forever and are, as the poll suggests older than in other online spaces.
I agree however that they shouldn't put so much focus on that target market they set themselves as a focus. They should embrace the diversity of this community and I am not talking about LGBT+ (they embrace that diversity), I am talking about the diversity in age.
There are many players that started with The Sims and have not stopped ever since, and I always feel that we are forgotten in many ways. For example, in the recent campaign with that cringe video where they didn't allow simmers over 25 to participate.
