It's probably CYA for any liabilities stemming from issues discovered/not fixed downstream after Google has addressed them. It's hard for Google to enforce offensively, but great for defense!
Ye I guess that's a good point! Sadly some people I chatted to don't really like this, since it constrains and confuses the finetuning aspect of Gemma - ie if we finetune on top of it, then Gemma v2 is released, do we have to do another finetune on top of the latest release?
