Ancestry. Who owns it and is it worth the membership?

Who owns Ancesty.com is a question we’ve asked ourselves many times and it’s a question we’ve been asked many times.  The other day, we decided to ask Wikipedia this question and below you have its response. (Except for the last paragraph, where we mention Mundia).  
“Ancestry.com Inc., formerly The Generations Network, is a publicly traded Internet company (NASDAQ: ACOM) based in Provo, Utah, USA. The largest for-profit genealogy company in the world,^[2] it operates a network of genealogical and historical record websites focused on the U.S. and nine foreign countries, develops and markets genealogical software, and offers a wide array of genealogical related services. In December 2010, the company provided access to more than 6 billion records and had 1.395 million paying subscribers.^[3]
In addition to its flagship site, Ancestry.com operates Genealogy.com, MyFamily.com, and Rootsweb.com, ^[4] and owns Footnote.com, which provides images of historical records. Family Tree Maker software, developed and marketed by the company, is the largest selling genealogical software in the world.^{[citation needed]}
Under its subsidiaries, Ancestry.com operates foreign sites that provide access to services and records specific to other countries in the languages of those countries. These include several countries in Europe (covered by Ancestry.com Europe S.à r.l.^[5]) as well as Australia, Canada, and China. According to the company's latest annual report, Spectrum Equity Investors is a majority owner in the business.^[3]”
And we can’t go without mentioning another member of the Ancestry stable, http://www.mundia.com/ , a global multilanguage family history network that is really making its presence felt these days.

For Australians is the information it holds worth the cost of the membership? We would love to hear your opinion.
