I'd argue that the market of 'people who are dating' isn't going to be dramatically affected by any particular company, and probably not even by online dating in general. They would have to be stupendously effective at creating long-term monogamous relationships to really move the needle there.

Marriage rates have been declining for decades, and serial monogamy seems to be growing (can't find good quantification of that). Successful dating services don't necessarily cannibalize their market.

My intuition is that providing an effective and enjoyable experience is going to provide far greater returns by gaining market share in a relatively inelastic market.
