Actually this is open source. This is what the term refers to. What you mean is that it's not free (libre) software, which is most certainly is not. They do not respect you and your rights: https://www.gnu.org/philosophy/open-source-misses-the-point....
sigh OSI was established specifically because they just wanted to share code and didn't care about GNU's 4 freedoms, so don't be surprised when the proponents of open source give you projects you can't even fork.
OSI was established specifically because companies got queasy over free software's quasi-religious rationale behind the "four freedoms" and wanted something that sounded a lot more pragmatic while effectively being the same thing.
Don't get facts twisted, it was never "if you happen to peek at the code, it's open"; it's the full freedom backing behind it. That's exactly what the OSD is about, which was linked int the parent, if you bothered to read it.
We're probably just talking past each other. The reason GNU comes off as religious is because they frame the whole issue in terms of human rights and moral imperatives (it is wrong to hide the source and we have the right to share). OSI prefers to frame it in terms of capabilities and transactional relationships (it's a win-win!).
The OSD is compatible with GNU licenses; I've read it before. That doesn't change the reality that by reframing the issue from rights to abilities, the OSI created the very environment where Winamp can be released as "open-source" while making forking illegal.
They are directly complicit in propagating the lie of open-source AI. If you can't inspect how it was made, including the actual training the data, you don't have the ability to understand how the AI was made. The choice of the lumber is part of how a chair is made.
Without the "I have the right to know what my computer is doing", there is nothing backing point 2 of the OSD. Without "I have the right to share", there is nothing backing point 1.
