What you describe is almost certainly what the legal team who drafted the terms and processes had in mind.
But there's two reasons to bring cautionary attention to it anyway:
1. As a user, I may not be okay with those terms as they stand and may not have the legal insight to have intuited them. In as much as I have a choice, because of those terms, I may want to use Gemini less/differently or look at other providers that have crafted less shrewd and defensive legalese and processes.
2. As a executive or manager at Google, whether working directly in feature management, or advertising, or government compliance, these same terms define the framework for anything I want to develop. What "makes sense" from a defensive legal standpoint today can the open door for an exploitative or otherwise unexpected use later.
I get what you're saying here in terms of plausible or justifiable "innocence", but that probably shouldn't get in the way of some critical personal reflection for users.
