IMHO Tom (now gone from the company) always held a strong opinion to open-source ALMOST everything.
From the outside, looking at the conversations that took place on Twitter after the initial release, he seemed to have a strong opinion on Atom being the same way, core inside github and rest is open-source.
Now that he's gone, that limitation is off and it's open source as it should have been from the get-go.
There's absolutely no reason this product won't be open source to the core, the more people actively developing on it the better.
Me personally, I haven't used it and I don't see myself using it ever in the future, but it seems like a very nice concept project.
