Badoo and Bumble in big war with Tinder.
When Match Group (fka IAC Personals) bought OKCupid (6+ years ago) for an astronomical amount of money, the OKCupid team had the task to copycat Badoo, but they failed in that mission.
IAC / Match Group "acquired" HatchLabs to "develop" Tinder copycat of Badoo.
Then Badoo backed Bumble to fight back and destroy Tinder (last December 2014).
