My conscience dictates I bring this up, I’m sorry if people see it as redundant or irrelevant.
Atom should be open source. Atom core should be FOSS.
Atom itself, if it’s as solid and extensible an editor as is claimed, will attract an incredible userbase on those merits alone. Assuming of course that GitHub integration is a default package, widespread adoption of Atom will drive GitHub usership. In addition, a free Atom will gain a larger usership than a paid Atom. and in the same vein, a FOSS Atom will gain more loyal veteran users than a proprietary Atom, again driving GitHub usership. An Atom that is any of [paid, proprietary, closed] will not offer these gains in the same way as a FOSS Atom.
GitHub has a platform, opportunity, and the resources to release the premier editor of the twenty-teens, and to make it FOSS. The publicity and respect GitHub stands to gain from releasing a FOSS Atom core is not to be ignored.
In terms of competition in what I’ll call the ‘editor market’, a FOSS Atom is a sublime killer, from what I’ve seen so far. An Atom which is closed in any way may not be. Also worth mentioning is the relatively recently introduced Brackets, an Adobe product which is based on some similar technologies, and is open source. a FOSS Atom core gives Atom a boost against Brackets as well.
This is something I feel strongly about, and I am sure other developers do too. I hope that the Atom team and GitHub give serious consideration to the market opportunity they are standing atop, and what a FOSS Atom brings to the editor landscape and to GitHub.
There are certainly things I’ve left out, so forgive me. I simply hope to illustrate my point of view.
