I do think the question of price discrimination is a really interesting one. Why hasn't anyone been successful suing for that? Why is Tinder being so obvious about it, do their lawyers no something we don't, or are they just that much more risk tolerant?
Movie theaters, theme parks, etc have all been using price discrimination based on age for years and never been prosecuted. I don't think Tinder's lawyers are afraid. They know it will cost a bit of bad press initially, but long term has little risk.
