Marginal use of Tinder probably decreases among people who feel excluded by the price discrimination and do not buy into it.
Marginal utility of Tinder probably increases for the college-aged target demographic if marginal use of Tinder by older (especially poorer and older) users declines.
At least, that's what I think Tinder is hoping will happen.
But in any event, even if they were going to move into "social discovery of anything" as a technology company, it does not follow that the current Tindr app and accounts is going to be used for "social discovery of anything," because it is obviously absurd to imagine that people want to use a hook-up app for "social discovery of anything." There is no market for people who are like, "Hey, I want to find the perfect drapes for my living room remodel and also at the same time look for casual sex."
