Is closed-source project like CMSity doomed to the death nowadays?

Seems it is very hard to spread the news about CMSity around the world, and acquire some user base of this project. Till now I did few commercial deployments of CMSity, however the cmsity.com page hits look really miserable.

I wrote mails to many CMS magazines asking to drop a note about my project. However only two of them replied and posted something on their sites about CMSity. So I still miss some more reviews that can put a breathe into the project. But it seems my mails are ignored by majority of big CMS related sites making very hard to promote new project like CMSity nowadays.

Since I believe this software presents great value and outperforms other popular solutions I consider releasing it as open-source, however probably not GPL but some license that will force the code to stay by the author (me), deny all the forks, making all community changes happen to be included in the source code base.

Open-source is a great idea, but I have seen too many projects that were just bloated, forked and spoiled by masses of developers that were just about put something of themselves in the project regardless of quality of the included changes, missing overall sense and directions of the project itself. That is why I decided to keep the code closed initially, while giving the licenses for free, but it seems non-open source project are just kicked out of the focus today, and releasing the source code is a "must" to gain the momentum.
