A platform to upload my freeware for users to download

I recently developed a script for Adobe After Effects that allows specific unique functions.
I made a website for this script that have video tutorial and preview elements.
www.motionengine.me

I uploaded the script which is ".jsx" file to sourceforge.com after I created a new project.
After a while I received an email telling that I have to provide the source code of my script in order to keep sharing it on the platform.
I told them that it's a freeware but it's not an open source so they told they have to delete it.

So I'm wondering, if there are other platforms that allows to upload freeware for users to download?
