A lot of teens in the US have jobs; I’ve worked since I was 14. At $10/month that’s like 1 fast food meal, and if you use it as your major chat platform that’s easily worth it for the convenience it offers you. And teens don’t generally have other major bills to pay.
God that’s so corporate-coded - instead of fixing your divisions so they are all profitable, just take your two successful divisions and squeeze them like you’re trying to get blood out of a stone.
