Why?

If they consistently screw over everybody else in the deal, people won't want to deal with them.

Hasn’t stopped them from dominating the market so far.

But I do believe they’re a shady company though.

Hubris before the fall.

IIRC, they own one of the few online dating sites that actually generates a profit: match.com. All of their other properties, particularly Tinder and OkCupid, are basically meant to get younger people hooked so that they will eventually convert to paying for Match.com.

This is absolutely untrue. There are many very profitable dating sites and apps. Tinder is a fantastic example of a dating app making money hand over fist since they began monetising, their revenue is in the hundreds of millions per quarter. Tinder is projected to be half of all Match groups revenue this year.

You mean the Tidner that will make $800M in revenue [0] this year?

OkCupid started as a free, alternative, non-traditional dating site based on a full-spectrum of interests compatibility. Unfortunately, post-acquisition, it’s becoming yet another Tinder/Match pics-first shallow hookup site.

OkCupid began monetizing before being acquired and that's part of what made them attractive.

OkCupid sounds exactly like PlentyOfFish, also acquired by The Match Group.
