To those who also plan to launch a software project. Taking money is fine. Open source (as in the source is open somewhere) does not have to clash with a paid license or any other form of monetization. There will always be negative voices. But there are also a lot of people who are happy to pay for your work when it has value to them. Nobody wins when you have to shut down your project because you can't make a living.
Anyone who's telling you that copyleft is problematic to business, isn't in the business of building software, but in the business of taking without giving back.
I am paid to make software, I wouldn't license my code as BSD. Because it lacks protection my business needs.
The core is: Create a business where you can be paid for the work you are doing and not depend on the work that you did in the past.
@tbroyer Depends on the model you choose. In our case it's more like "source-fully-available-and-as-open-as-possible-while-still-under-a-commercial-license" whereas I've seen other models that take it a step further.
