Many investors are betting against Match Group, the parent company of Tinder.

I agree. Because:

• Several complaints about Match dot com suggest ... database is full of old & inactive profiles, scammers, fake profiles, etc!
  Perhaps Only way to sustain that huge revenue is creating fake profiles from inside to entice customers to subscribe. ???
• Badoo backed Bumble to fight back and destroy Tinder (last December 2014).
• Match Group overpaid for PlentyOfFish last July 2015 (It was insane, USD 575 Million for PlentyOfFish that past its prime 3 years ago). 
• The Match Group had been doing all wrong, acquiring rotten companies to show illusory success to its investors.
  Perhaps Tinder steals paid members from Match, OkCupid and PlentyOfFish, cannibalizing it!
  The Match Group is only a collection of old and obsolete online dating sites: Match, Meetic, Chemistry, OkCupid, LoveScout24 (FriendScout24), OurTime, HowAboutWe, PlentyOfFish and many more and all of them are past their primes, reached operating ceiling and they are in decadence.  
• Match Group has a big debt now, in the range of USD 1.2 Billion

Match Group still in talks to acquire Bumble with a valuation over USD 1 Billion ?

Last May 2016, I suggested USA FTC investigate several online dating sites for misleading statements, false claims, overpromises.
Like Match, eHarmony, Zoosk, OkCupid, EliteSingles (Affinitas GmbH.) copycat of eHarmony, Tinder and others.
