There is a recent report that in the USA alone $12billion is spent annualy by business for software licences not used.
“The vendor 1E polled IT managers in an attempt to answer this question, and the number produced is a big one: $15.3 billion in the United States and United Kingdom, including $12.3 billion in the United States alone. That number is the amount of money spent annually on maintenance for unused software and shelfware.”
What could you do with $12billion? I can feed myself for $3 per day so I could feed 4 billion people for one day… I could build 120,000 modest homes. I could pay for 300,000 university educations. $12billion is a lot.
With FLOSS, the licence usually costs $0 so business running on FLOSS could save all of that $12billion and it would only take a small effort to migrate to FLOSS. Business has made mistakes along the way by not migrating sooner and buying licences instead of making their own software but it is never too late and $12billion annually saved forever will pay the total cost of migration in a few months or years, leaving all of eternity to spend the money on other things that bring value.
In education I have seen tons of software sitting unused on shelves after PCs were retired or licensing codes lost. Staff turnover and human error result in enormous amounts of money being spent foolishly. Switching to FLOSS would make acquiring and managing software so much easier.
