That is
open to debate,
English works like this, you put a word in front of another, and it qualifies that word.
Open, is such a word, it is a verb. You don't get to call it a specialist term, because it isn't, and you don't get a trademark on it, for precisely the same reason.
Open source, means the source is open. It is one of many freedoms. OSI-open source is 4 of them. Copyleft is 5.
One, open, two three four, free, five copyleft.
Open isn't the first freedom, so why is just (1)?
What is interesting here is that open does not even guarantee freedom zero, to use it in any way you please.
I never said it was free software, i said it was 3/4 of it. If you cut off a human at the axles up, you are left with 3/4. Platon would disagree, and make a reasonable point that we could get into.
In the case of the pyra hardware license, it is a meaningful 3/4, if you were going to lose one out of 4, or even 5 for copyleft, it would be the non-commercial bit.
Saying the pyra hardware license is open, is true, but it isn't that meaningful, not because that freedom isn't important, and valuable even alone, it is because
Open is not a specific word. It means access. Access to whatever word you want to qualify as open after it, be it open source, open schematics, or what have you.
It means free as in freedom software no more than use as you please, modify, or share. It means in most sentences, or without an implied understanding, libre software at the exact same rate free software means gratis. Because yes, as you are pointing out, talking about free software in less than free as in freedom, as per the definition, is vague, meaningless, possibly devious, or all of them.
And open is just that, and im a certifier. To qualify as zingu- open source, it must be open, can be vague, meaningless, possibly devious, or all of them.
Edit: Btw, oshwa deals with hardware. 'Open hardware' is, albeit for the time being, a specific term. It is a social term, so you could hollow it out if you wanted to. That will probably happen, as the different open hardware licenses differ widely in terms of grasp, legality and protection.
So, to counter your point. No, FSF or OSI standards do not govern open source. I believe the FSF coined Free software with the definition it holds today, but that is beside the point.
Yes, free software is a glass-is-always full ordeal, but open, or open source, does not at all rule out non-commercial.
While free as in freedom software is no longer free once it is non-commercial, open, or open souce, is just as open, or open source if it is non-commercial.
You are cherry-picking organizations, and confusing it with hardware.
There are a whole lot of open source licenses that are non-commercial. The MAME-license comes to mind. At-least one open hardware license has been non-commercial

Even licenses not intended for software can be open, and non-commercial
