My answer to that question is that the cost of the insurance varies based on demographics (you didn't mention the biggest variables like driving record, vehicle type, loan/lein and collision) while the Tinder service cost is basically the same for all users.

The most sense it makes for Tinder to do is to chage men more than women, which they already did.

Insurance cost is determined based on actuarial tables, whereas Tinder probably doesn't even consider the size of anyones table.
