An anonymous reader writes "Of the 118,023,363 sites surveyed by NetCraft so far in the month of May, just over 70 million of them wouldn't work if open source software were to disappear. A Day Without Open Source gives several examples of what would break [and pokes fun at MSN]. However, this got me to thinking. The real question should be: Could we live without open source? All of the proprietary companies that bitch about open source should read this and think about how stupid some of the statements they make are."
