Mainly because they were trashed and destroyed by India Inc. in the 2008 Wall St. collapse.
One of the Indian Mafia who caused the collapse is now sitting in Federal prison for sabotaging Fannie servers with logic bomb code.
Companies can only take so much destruction before they die.
Fannie surived, but just barely, and is stuggling today to survive.
India Inc Mafia did irreparable damage to Fannie + it may be gone soon.
Smartest people in the world our “briliant companies” can’t do without.
Others, such as Lehman, were not so lucky and were looted and consumed by the India Inc Mafia.
Gone.
Forget Game of Thrones. We’re talking epic Chain of Blame treachery.
