I am in agreement. However, I do believe that a large portion of the community here is also missing a key point: Facebook was more open five years ago with their AI research than they are today. I suspect this perspective is because of the massive influx of people into AI around the time of the ChatGPT release. From their point of view, Facebook's move (although dishonestly labelled as something it is not) is a step in the right direction relative to "Open"AI and others. While for us that have been around for longer, openness "peaked" around 2018 and has been in steady decline ever since. If you see the wall of text I linked in my first comment in this chain, there is a longer description of this historical perspective.

It should also be noted (again) that the value of the terms open science and open source comes from the sacrifices and efforts of numerous academic, commercial, personal, etc. actors over several decades. They "paid" by sticking to the principles of these movements and Facebook is now cashing in on their efforts; solely for their own benefit. Not even Microsoft back in 2001 in the age of "fear uncertainty and doubt" were so dishonest as to label the source-available portions of their Shared Source Initiative as something it was not. Facebook has been called out again and again since the release of LLaMA 1 (which in its paper appropriated the term "open") and have shown no willingness to reconsider their open science and open source misuse. At this point, I can no longer give them the benefit of the doubt. The best defence I have heard is that they seek to "define open in the 'age of AI'", but if that was the case, where is their consensus building efforts akin to what we have seen numerous academics and OSI carry out? No, sadly the only logical conclusion is that it is cynical marketing on their part, both from their academics and business people.

In short. I think the correct response to Facebook is: "Thank you for the weights, we appreciate it. However, please stop calling your actions and releases something they clearly are not."
