Genealogy.com sold and still sells user-submitted family trees online and on CD. (If I recall correctly, they used to be about $30 each.) The site is now owned by The Generations Network, Ancestry's parent company.
I am an Ancestry subscriber, but I'm not familiar with every feature and database. I recall there being a premium online tree-building section only available to paying customers; something bigger and better than WorldConnect.
I know people are willingly uploading the data and I don't know how a hugely popular site would go about offering free online tree-building, but both of these kinds of services bother me. Obviously not enough to not subscribe to Ancestry, though. I don't know why people use these premium services other than perhaps ease of use, but that still wouldn't change my mind. I just do not like the idea of the data being sold like it is.
So now Ancestry is "caching for cash." Not surprising considering the aforementioned premium services and knowing that search engines, namely Google, have made a killing do this. Really, is it that shocking?
This reminds me of the guy who was hawking software to create bogus genealogy data and web pages. His beef was with Google making money off of his work and trying to gum up their results. I bet he's none too pleased with Ancestry right about now.
