I'm not following your point. By your own admission, installed software in the enterprise is not as affected by piracy, so it seems to back up my point that there must be some other factor that prevents a commercial, installed application ecosystem to flourish in the developer tools sector. I still think the service-oriented nature of github has a large effect. It's one thing for a open source clone of github to exist, it's another thing if it's something that IT needs to install and manage in your organization. On the other hand, your text editor, debugger, etc, are all things that IT doesn't care about beyond if it is installed and runs. So, the value of B2D is beyond the functionality of the tools per se but it's also the additional benefit of not having to run the service yourself to get its benefits. If that additional benefit were missing, the github-clones would thrive because they would be very close to equivalent in terms of time/cost/reward tradeoff for all members of an organization.
