Open Source Software (OSS) is not the same as Free Software (FS). And even with Free Software, the free doesn't mean necessarily Gratis. There is something called Free Open Source Software (FOSS), but even there the Free doesn't need to mean Gratis. Either way, I don't think there is something wrong with having a paid service, while still having your code being OSS. It means that you can access the code, and use the product for free, but you might want to pay for the services the company might offer on top of it. Not that I know if that's the case here, but you know, it's possible.
