Of course, neither of us knows how many of us are on either side of this. But I guarantee that WoTC knows. And considering how well 5e is still selling after all this time, I'm willing to be that they know what they are doing.Neither do you. Neither do any of us. No one's opinion can be taken to represent an entire demographic. But I can say that there are multiple older gamers on both sides of this particular divide.
Edit: And I know in the past you've talked about how you don't like hearing what you like criticized. Imagine how much fun it is to hear that what you like is 'childish' or 'targeted at the very young'.
