No, because excluding commercial users is a field-of-use restriction, and you're not FOSS if you only offer a license which imposes a field-of-use restriction. Which is fine! Just don't call it FOSS.
Furthermore, it's really hard to define what non-commercial actually means. Creative Commons spent something like a decade trying to scope a reasonable definition and eventually ended up essentially punting. With a few exceptions like (arguably) secondary public education use, pretty much any non-trivial use has some commercial component.
There is no semantic game, open source software is a term of art with a much more specific meaning than the source being available. If you find this draining then you can simply stop trying to misappropriate the term.
In the case of the Free Software Definition, this makes perfect sense: the FSF wants people to have certain freedoms at work, as well as freedom in their personal lives.
The other challenge is that turning an open source project into a proprietary project isn't as simple as changing the license and asking for money. You need to build an entire business from scratch, and learn to close sales somehow (or sell to consumers). This will take up at least half your time.
The AGPL is not a non-commercial license, but it essentially functions as one, as most companies aren't willing to comply with it. There are some projects that make their code available under the AGPL, and also let users pay to get access under a different license. Grafana is an example.
By definition there aren't any, but MAME used to be distributed under such a license. I think Debian in particular has been pretty successful at exerting pressure to either relicense or replace software with non-commercial restrictions.

I'm sympathetic but this is an uphill battle unworthy of fighting, in my opinion. Canonicalization of "open source" (versus "OSI Approved Open Source") is overreach of a an organization suffering from declining relevance. OSI is not helping to move the needle on licensing, and has effectively caused the industry to become frozen in time with the same stagnating licenses we had 10-15+ years ago. There's no innovation here, and I'm just tired of this. Instead we have demonic machinations like the BSL growing in relevance because there's no better alternative. I'm just so sick of it.
If you asked any reasonable person what the opposite of "closed source" is, you're going to get a uniform answer from the vast majority or respondents, and a small, irritating answer from a small, increasingly irrelevant group group of folks. I understand the distinction that "source available" aspires to achieve, but it's such an unappetizing term of art that you may as well call it "I can't believe it's not open source".
Champagne, Chocolate, Open Source... they're all noble but doomed uphill battles in colloquialism. Everyone knows what you mean.
If you want to be correct, be truly pedantic, instead of shifting the ambiguity: French Champagne, Belgian Chocolate, OSI Approved License.
Don't get me wrong, I'm a diehard FOSS supporter, I sponsor and contribute, I encourage my employers to be good global citizens with respect to FOSS and have complied with licenses by releasing modifications under appropriate licenses. I even pay Drew DeVault money. But ultimately he and everyone else arguing to enshrine the term "open source" will couple the fate of their opinions to that of the OSI and at best, it will all be a footnote in the pages of history.
Will we be using the same OSI approved licenses in 10, 50, 100, 1000 years? Will the OSI permit term "open source" to be used to refer to something other than the current licenses?
The reason to defend the definition of "open source" as it currently stands is to prohibit organizations from profiting from the accumulated goodwill of the open source community and movement without actually adhering to the ethical standards of that movement. We've seen in the past that companies will release source under an encumbered license and claim to be "open" as a result -- the FSF and OSI were founded in response to that type of maneuver.
As far as I can tell, it's been a success. The recent batch of nonfree licenses have all had to emphasize that they are not open source in the face of public backlash. Making euphemisms like "source available" unappetizing is exactly the point.
Furthermore, the OSI is just a group, as is the FSF. If the OSI and FSF folded tomorrow the definitions of "open source" and "free software" would not change. It's not necessary for the OSI to approve a license for the software to be open source, so "OSI Approved License" is not sufficient. "Licensed on terms compatible with the Open Source Definition" might be more accurate, but "open source" seems like an adequate shorthand.
> It's not necessary for the OSI to approve a license for the software to be open source
I agree with you, but this is a controversial opinion which is the root of my frustration. OSI tries really hard to own "open source" as a term and while I'm not against the OSD I am against the gate keeping I see.
Ghostscript used to have the most recent version under a non-commercial license (AFPL) and older versions relicensed to GPL, before they switched to AGPL only.
