I think you have your websites confused.
familysearch.org is the LDS site. Ancestry is a site owned by a company that was publicly held until a few months ago, when it was taken private by a hedge fund. These two sites have nothing in common.
Ancestry's main focus, therefore, is to make a profit.
We are all waiting to see what repurcussions that this change in ownership will cause.
One issue of concern is that the monthly subscription for ancestry is the "cash cow" of this operation; whereas FTM is a sideline kept as an alternative gateway for people into their "cash cow". How much effort by the new owner is going to be made to make FTM the best and most robust stand-alone application is yet to be seen.
An interesting observation is that after years of annual versions, FTM skipped one for FTM2013. It was a marketed as a "great gift" to FTM2012 users, as a rather modest update to FTM2012 was free and took the place of what would have been the FTM2013 version.
Does that mean that corporate has decided that the little gateway to the ancestry databases (FTM) isn't worth the dollars of investment to make meaningful upgrades? That they are better off using that money to acquire more databases and "partners"? and therefore focusing on the on-line trees as the main app for users? Inquiring minds want to know....
