Compelling business arguments for going Open Source

Adaptavist recently announced that they're licensing their Confluence plugins for free, and moving to an Open Source model. In short, here's why:

We've been listening to the feedback from our customers and also our own staff:

• Smaller customers don't want the expense of commercial plugins on top of Confluence
  
• Larger customers don't want to waste time dealing with software licenses
  
• Transactional customers hate our sales process
  
• Non-transactional cstomers want us to focus more on their needs
  
• Customers who don't want support don't want to subsidise those who do
  
• Software licensing inevitably forces vendors to start adding increasingly useless random features to products to drive license sales (think "Microsoft Office"...) - we really want to avoid such insanity
