Public/private partnerships make business instruments of government. As an instrument of government you are not free to act as you would if you were operating freely.
Public/private partnerships began corrupting American government in the mid-1990s during roundtables that Clinton and Gore held to get business to cooperate with sustainable development, among other things.
Public/private partnerships are boasted by the white house still today. They are a form of fascism and should not be allowed by the American people, but most Americans don't know this corruption exists, or if they do, they are getting paid in some form by the government to carry out the government's agenda. This is NOT freedom.
Example:
The Empowerment Zones/Enterprise Communities (EZ/EC) Program represents a new way of doing business for the Federal government.

These kinds of deals are responsible for the trend for local governments to condemn property through eminent domain (another program that is easy to abuse) to give to private developmers. Then the developments are funded again by the government because they are usually developments the free market won't support.
Another example of loss of freedom is the "smart growth" anti-free market, anti-property rights programs pushed on citizens by federal,state and local governments.
In smart growth cities, urban boundaries cage people into a particular geographic area,preventing land owners outside the area from using their land for homes. The people inside the area are forced by the government, either by law or by paying off local officials to only build and live in "cluster developments" or on transportation hubs. This type of development is going on in Sacramento CA right now. Taxpayer money is used to pay cities to build in such a way that private automobile ownership becomes untenable. They do this by refusing to keep up the infrastructure, paving roads and adding lanes to support the growth they force with infill development. Then they repurpose streets for bicycles and buses, or redesign them with "traffic calming" devices that make driving hazardous and tediously slow.
Another neat little trick they use is a compact with the developer, either granting money outright or by granting tax incentives, so that the developer will not build in enough parking for their apartment complexes. Some developers even sign covenants with the government to restrict parking, water use and energy use in their buildings, that is enforced on the tenants.
They don't necessarily enact a law that says "you are not allowed to own an automobile" or you only get 17 gallons of water a day per person, but when they coerce local and state governments to go against all reason and encourage them not to protect individual rights but to enact collectivist anti-car housing policies, the outcome is the same. Freedoms are lost.
