"Cancelling the Commons" is a rumor started by self interested preferred shareholders with little if any evidence offered to support this self serving rumor/hypothesis.
The government "had an opportunity" to "cancel the commons" and declare them bankrupt with no value, but there were good reasonss then, and now, that is simply highly unlikely because:
1. The company is not bankrupt, continues serving millions of homeownerss each year, with new ones added daily. Instead, FNMA is highly profitable, and so much so, our greedy government officials looked to confiscate our earnings for their socialization purposes, such as Obama care.
2. "Cancelling the commons" and bankrupting the company would mean our government would be taking on the debt of about half the homes in America, around 6 trillion dollars worth added to the federal deficit. The government does not want to assume the gse twins trillons of debt.
3. Even if the government didnt care whether or not we were bankrupt, and just decided to confiscate the money anyway, and was willing to add 6 trillion in debt to the federal deficit, "the courts" especially the US Supreme Court is a barrier for them to do that. Our constitution provides that its illegal for the government to "take" private property without just compensation.
Make no mistake "Cancelling the commons" means a "government taking" of private property and is against the constitution.
If our government is allowed to "take" fannie mae shareholder property, then they may also take "Apple shareholders, Tesla shareholders and every oth4er company's property, likewise.
There would be nothing stopping them from taking the rest of everything you own also.
It would mean completely converting the American democroacy to socialism or communism.
