propriety software

Currently computer and internet users have access to a wide variety of software, which allows them to achieve their desired result, whether its reading an article online or finding a location on the earth.  Currently there are both open source software as well as propriety software.  Both types of software carry there own sorts of advantages, though I believe that propriety software is superior to the open source software.  Propriety software provides individuals with the software they desire, but does not allow the individual to change the make up of the software.  The best example is that of wikipedia, any individual has the ability to log onto wikipedia and change a certain form of information at their will.  This hinders the original make up of the software as well as makes the software less reliable.  However propriety software is not like this as the individual using the software cannot make changes t the internal structure of the software.  In my opinion this make propriety software much more reliable, like such examples of adobe reader or google earth.  The software programs allow an individual to gain access to an online document or the ability to pin point a spot anywhere on the earth, though the internal structure of the software cannot be changed and therefore I believe propriety software is much more advantageous then open source software.
