That's a key thing about it not suddenly going away, being open source you can download the sourcecode if you ever really felt the need or desire to contribute. No company behind it, just a team of contributors....subsurface is good. Given it's an open source app (started by linus at that) and it is able to export into other formats (or other apps are able to import it's format) I have no problems with it.
