I think that that in addition to the price-setting / risk-spreading nature of the "monopoly," they're also trying to control new "experiences" as it relates to dating. OKCupid / Match offer a fundamentally different experience to Tinder or HowAboutWe. IAC seems to be making a macro-bet: we don't know what online dating will look like in 5-10 years, but we want to control it. Interestingly, they "incubated" Tinder via Hatch Labs (where I was an employee). Pretty impressive control of that vertical.
