HealthCentral buys WellSphere, but did they get a lemon?

The medical blog aggregator WellSphere has been coming under fire for distributing blogger content without sharing traffic or revenues with the authors. 

Online health site HealthCentral recently announced that it was buying WellSphere, as the consolidation in online health sites continues.  
Val Jones writes about the treatment she received from WellSphere, and discusses the controversial fine print in the Terms of Service agreement.  She also notes a distict lack of benefit from joining the network that others are similarly expressing in this Twitter thread. 
Is WellSphere a scam, and is its leadership laughing all the way to the bank after the HealthCentral acquisition?
