That's a fantastic! I don't mean to insult, but the likelihood of the software being shared freely by a user increases with success. Your situation is an exception. And likely contributing factors are the specific field and sophisticated, like minded customers.
Thanks. But actually, no, we write software for many fields and most of our customers are certainly not sophisticated, nor do they care about our philosophy (to most of them, open source means roughly "not as good but cheaper").
It's true that our customer base is not very large, though.
