> Edit: Notably it seems some commenters here confuse the idea that FLOSS will allow for forking but open source does not necessarily do so.
This is not a confusion on their part, but on yours. "open source" is defined as it is deliberately, in response to organizations trying to confuse their users about the terms of the software they've offered. What you see today is the outcomes of years of debate from decades ago, and trying to have it mean something different would require a similar debate to change well-settled terms.
If you want to talk about software where the source is available but may not be forked or redistributed, use terms like "source available" (which has its own Wikipedia article https://en.wikipedia.org/wiki/Source-available_software, showing that this isn't just my term or those of the other commenters here).
