Switching to an open source model would mean that only 1% of the users would pay anything. To make that viable you need a good business model for a much larger or a different market. The business model is vastly different with a vastly different product.

Just open sourcing the thing is an easy way to kill an existing company, which now has a small, but paying customer base.

No, no; it wasn't was I meant; I clarified in the last one; release things for free for already non-paying customers for non-commercial use only, Qt style. I am hard to believe Boeing would count in that group :).

How do you enforce that? Experience shows that most companies ignore that code is only for non-commercial use and it's hard to enforce for small companies.

I also doubt that all customers are like Boeing.
