Checked.

  The more open source software out there the better. And the more open weights or even over source AI stuff the better too right?

is it not open assembly?

open weight models are better than open-assembly binaries (as you put it) because models are grown like plants, you can shape the open-weight model in a direction you want by feeding it more data and compute (aka finetuning).

which is something that is impossible in a binary.

embrace the new paradigm and it's tradeoffs. without scoffing at semantics and criticising from an armchair.
