I've upvoted this - I made desktop graphics software that I thought would be used by young web designers, but ended up being popular with a 60+ older demographic. (Think along the lines of "scrapbooking".)
They're wonderful people, but there was a lot of pressure to keep prices down because "I'm on a fixed income". That makes it harder to invest more time in design, even though you need to since they're your main market.
(I'm even aware of a couple of elderly 'customers' where "my son gets me all the software for free!", nudge wink torrents.)
Elderly users often require a lot more customer support and hand-holding than a customer in their 30s. Some really enjoy the customer support since for many of them it's one of their few social interactions of the day. Which is fine, but if the product also has to be cheap to meet a fixed income, it's hard to be profitable and have great design and excellent non-rushed non-offshored customer service.
Of course, not all customers are the same. I'm sure there were wealthy & savvy elderly customers too, but I didn't know how many because they never contacted customer support & so I never got to know them personally.
