The original charter is nothing more than a marketing copy. And companies are legally allowed to change their marketing copy over time and are not bound to stick to it in behavior. The marketing was for the investors and they should be the first to know that such promises are subject to how reality unfolds. In other words a team can raise money by promising milestones but they are allowed to pivot the whole business and not just abandon milestones if the reality of the business demands it.
