Ask Slashdot: Can Closed Source Software Transition To the GPL Successfully?

Posted by samzenpus on from the making-a-change dept.

colinneagle writes "Open Source guy Bryan Lunduke has experienced the difficulties of migrating a successful closed source project to an open license first-hand, but still believes — or at least wants to believe — that it can be done. He writes: 'Occasionally, someone makes a go of it, to take a good piece of closed source software and release the source code under a nice, open license. In fact, I did just that about a year ago. I tried to take a software development tool (along with some video games) that I had developed (and was earning a good living from) and migrate them to the GPL with continued development funded via donations. The results were...disastrous. Within a very short period of time of going Open Source, the total funding for the projects fell to less than 20% of what was being brought in via sales when the software was Closed Source, which almost completely impeded the ability to fund continued development. Luckily, I was able to recover and get things back on track, but it was definitely not a fun experience.'" How viable is migrating a closed source project to something open?

    OpenOffice started as StarOffice. Seems pretty viable.

      If you look at it from an Open Source perspective Open (and Libre) Office are great projects.
      Looking at them from a business perspective, it is hard to make money from OO.o. There is a reason Oracle dumped it at the Apache foundation.

      True, but TFS is actually asking a slightly different question to the headline.

      The full question is "Can a commercial software project continue to bring in enough money to fund itself if it goes open source?". And that is a very good question.

      As regards Star/OpenOffice, Sun bought Star Division. They made StarOffice 5.2 available free (as in beer) but when they opened the source, a **lot** of the code had been licensed from third parties. Sun didn't have the rights to open source that, so they had to subsidise OpenOffice for years while the code that couldn't be opensourced was rewritten. I'd be astonished if they ever covered their costs from it.

    Surely, if your business model relies on selling copies of your software, then going GPL is not going to work. What was he expecting?
