Comparison With Closed Source
The debate over open source vs. closed source (alternatively called proprietary software) is sometimes heated.
The top four reasons (as provided by Open Source Business Conference survey) individuals or organizations choose open source software are: 1) lower cost, 2) security, 3) no vendor 'lock in', and 4) better quality.
Since innovative companies no longer rely heavily on software sales, proprietary software has become less of a necessity. As such, things like open source content management system—or CMS—deployments are becoming more commonplace. In 2009, the US White House switched its CMS system from a proprietary system to Drupal open source CMS. Further, companies like Novell (who traditionally sold software the old-fashioned way) continually debate the benefits of switching to open source availability, having already switched part of the product offering to open source code. In this way, open source software provides solutions to unique or specific problems. As such, it is reported that 98% of enterprise-level companies use open source software offerings in some capacity.
With this market shift, more critical systems are beginning to rely on open source offerings, allowing greater funding (such as US Department of Homeland Security grants ) to help "hunt for security bugs."
This is not to argue that open-source software does not have its flaws. One of the greatest barriers facing wide acceptance of open-source software relates to the lack of technical and general support. Open-source companies often combat this by offering support sometimes under a different product name. Acquia provides enterprise-level support for its open-source alternative, Drupal, for instance.
Many advocates argue that open source software is inherently safer because any person can view, edit, and change code. But closed-source software—and some research—suggests that individuals that aren't paid to scrub code have no incentive to do the boring, monotonous work.
A study of the Linux source code has 0.17 bugs per 1000 lines of code while proprietary software generally scores 20–30 bugs per 1000 lines.
Ajzen's theory of planned behavior explores the link between attitudes and behaviours. According to a pilot study of organisations adopting (or not adopting) OSS; several factors of statistical significance were observed in the manager's beliefs in relation to (a) attitudes toward outcomes, (b) the influences and behaviours of others and (c) their ability to act.

Famous quotes containing the words comparison with, comparison, closed and/or source:
“In everyone’s youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.”
—Henry David Thoreau (1817–1862)
“The comparison between Coleridge and Johnson is obvious in so far as each held sway chiefly by the power of his tongue. The difference between their methods is so marked that it is tempting, but also unnecessary, to judge one to be inferior to the other. Johnson was robust, combative, and concrete; Coleridge was the opposite. The contrast was perhaps in his mind when he said of Johnson: “his bow-wow manner must have had a good deal to do with the effect produced.””
—Virginia Woolf (1882–1941)
“With two sons born eighteen months apart, I operated mainly on automatic pilot through the ceaseless activity of their early childhood. I remember opening the refrigerator late one night and finding a roll of aluminum foil next to a pair of small red tennies. Certain that I was responsible for the refrigerated shoes, I quickly closed the door and ran upstairs to make sure I had put the babies in their cribs instead of the linen closet.”
—Mary Kay Blakely (20th century)
“We are constantly railing against the passions; we ascribe to them all of man’s afflictions, and we forget that they are also the source of all his pleasures.”
—Denis Diderot (1713–1784)
