The short answer is that the cost of transparency is things change. We did our best to be transparent on the journey to going live but with that we knew things would be different in some situations. Sometimes people would be happy and sometimes they would be upset.
It’s the cost of transparency.
Edit: to elaborate - game development is full of change. There are a million reasons why you set out with an idea and it evolves over time. This is common in every game. We shared as much as we could. Some things change. So the cost of transparency is that some things we said become not true, not because someone was dishonest but because it changed over the course of development.
