I’m part of that group. If OSI and FSF want to control the definition of something, they should make new and unique terms, not just attempt to take over a concept that predates both of them.

Call it OSI-Approved Zero-Restriction Licensing or something.

Whether that term existed before it or not, that's what people understand now. When talking about FOSS software, those definitions are what people expect - by a humongous wide margin. Calling those terms 'generic' is the weakest argument I have heard to dismiss the rigorous meaning people attach to it. Standards are centralized for a reason - so that everyone is on the same page. There's nothing wrong with it. Claiming otherwise isn't anarchy - it's an intent to cause confusion*.

Trying to subvert those definitions and trying to pass of non-commercial as either Free software or Open source software are in my opinion, rather malevolent distortion of an existing paradigm meant to help only the companies that I mentioned before - those that want to exploit the FOSS ecosystem, but without making the necessary compromises. It's an attempt to exploit a widely-held belief based on a rather vague and frankly misguided technicality.

Non-commercial sources already have an appropriate term - 'source available'. It's another generic term with a well-defined meaning. Hijacking the meaning of 'open source' and 'free software', instead of using this one is the perfect indication of the misleading nature of the hijack. And looking at the prevalence of this, I'm starting to suspect a widespread astroturfing/misinformation campaign.

Funny, that’s how I feel about OSI stepping in to claim control of that term.

Funny, they just used a generic term to mean something, while the exploiters use the term that means something to hide their true intentions and profiteer.
