In addition to being riddled with scammers and "escort" services in some regions and choosing to do nothing about it, older men are charged more for using Tinder's premium service: https://news.ycombinator.com/item?id=24129986
I do not respect Tinder at all. They have scummy practices and I actually got upset with Apple for giving them featured spots on the App Store so often. Talk about biting the hand that feeds you!
On the other hand, Apple unconditionally refunded my Tinder in-app purchase when I fell to one of their scams.
Seeing Tinder in any group will just make me automatically align with that group's antipode.
