Perhaps we could rephrase my statement to "there are a bunch of green checkmarks on github that may or may not mean anything depending on who you ask."

Wait, what files are you reading? https://github.com/google-deepmind/gemma/blob/main/LICENSE

(Even then, releasing some source code under Apache-2 does not make a model "open source".)

Ah I found https://ai.google.dev/gemma/terms

Yeah, definitely not open source, even if they had released all the training data.
