The Dragon spacecraft is the first vehicle which has been built primarily with private funds, where the "ownership" of the vehicle does not belong to a government agency. When this vehicle returns to the Earth, while NASA will get all of the stuff that is inside of the vehicle, it doesn't "belong" to NASA. In fact SpaceX has even hinted that this particular vehicle might see a 2nd or 3rd flight in the future (in terms of the capsule itself). NASA's COTS contract requires a new vehicle for every flight, so those subsequent flights will likely go to paying commercial (read non-government) customers, but the spacecraft doesn't "belong" to NASA.
The comparison here is more like how commercial airlines can lease their aircraft and crews to other people, including government agencies.
In the case of most of those "privately built spacecraft", there is a huge difference between them and the Dragon. For things like the Space Shuttle, the Apollo spacecraft, or even things like the probes to other planets, they were designed by NASA engineers where all of the specifications and design requirements were decided upon by NASA management and had NASA personnel at nearly all levels of production. Any "private" companies were really contractors and sub-contractors who followed the lead of NASA supervision.
Also it is important to point out that the other spacecraft that have flown to the ISS by American companies have also all been "owned" by NASA. If you tried to buy a Space Shuttle from North American-Rockwell International (yes, I know those companies are now owned by Boeing), you would have been politely told you simply can't buy them at any price. There were some people who tried to buy a Shuttle in the 1980's and simply couldn't. In the case of the Dragon, SpaceX will gladly sell you one and even help you out with the government paperwork needed to be able to use it and help schedule a launch for you as well. They will even help you through the process if you aren't an American (which does add paperwork and some hassles, but it can be arranged).
I'll admit that commercial companies have been involved with the construction of spacecraft in the past, but this is something new. How different it can be will be seen with other projects that SpaceX is doing that will be completely private for-profit ventures not involving NASA at all.
