It is a technical term defined by a bunch of people who got together and agreed that their opinions (however educated they may be) are more correct than other people's. That's extremely subjective, and not universally accepted.
Technical terms have definitions that transcend the opinions of people who use them. When I say "byte", everyone knows exactly what I mean, as it's a unit of measurement. When I say "agile", it could mean any number of different things, depending on context. When people say "open source", the thought that comes to a lot of people's minds is simply "I can see the _source_ code, because it's out in the _open_."
It's subjective, and, frankly, annoying. It shouldn't matter how something is licensed, because the most important aspect of software is whether or not it provides value and helps me do my job. Bickering about semantics doesn't get work done.
