The "Tinderslut"[1] comment says a lot about how Rad and Mateen view the women who use their app. It's consistent with Wolfe's claim in her complaint that Mateen told her it would be "slutty" to be a female Tinder co-founder, because it was an app people used to hook up. As an aside, Mateen exhibits the textbook Madonna-whore dichotomy. To him, women are either someone he can see being a wife (Wolfe pre-breakup), or…
Isn't the point of the app to enable promiscuity. "Slut" is a word for a promiscuous woman, sometimes used for a prostitute, sometimes used of men (in UK at least). Surely they viewed the women who use the app as wanting to have free and easy sexual encounters, ie behave like sluts?
When the slang that associated their app with the actions of those using it, viz "tinderslut", was popularised were they not justified to consider that an achievement - the app was clearly notorious for enabling promiscuous behaviour, exactly the behaviour it was designed for.
There seems little controversial in them calling active users of their app sluts (men or women).
For me there is much to hate about the app morally but it seems rather silly to get upset that the designers of the app that people use to seek out promiscuous sex consider their users to be in to promiscuous sex?!
