It's so fundamental they didn't include it in the definition?
>Open source is not merely a license choice.
Yes it is. The OSD only deals with licenses, therefore whether a software has a "community" has no bearing on whether it's open source.
You're claiming the terms laid out in the OSD were motivated by hopes of cultivating a community, but the reasons behind the document are immaterial to this discussion. It only matters how "open source" is defined, and it's plainly not defined by the presence of any community.

I didn’t say that. I didn’t bring up the OSD at all. In fact I was explicitly talking about a broader concept than simply license terms from my very first sentence. You were the one that started talking about the OSD.

The OSD defines criteria by which software licenses can be considered open source. It doesn’t define the movement as a whole.
