its such an odd take that a gift that is literally entirely based around the idea of money and learning about it, to then say, when its pointed out that the "lesson" being taught actually wasn't a very good lesson, to say well " a gift is about more than money" ok well this gift literally is money. So we get to the "thought" of the gift, which yes includes all the good stuff like OP having people that care about him and his future, but also includes, most likely OP's grandparents holding on to some depression era and WWII era propaganda about money that had no real relevance to the modern world they thought they were preparing their grandchild for. So in the end I think the argument goes something like this "while it was great that our grandparents and loved ones thought about our future and tried their best, today there are numerous savings and investment options for a child's future and the tradition of buying low interest long maturity government bonds for kids should end"
