Its not good hidding some members of the project its like they saying that the project will do unnecessary things thats why they need to hide of their upper members of the team.
I never liked all these "hidden" members who come out of nowhere. Crypto projects are all about transparency and if I ever find out that some of the team members of a project I invested in are not the real team members or there are additional team members which were never mentioned then I'd immediately withdraw and sell everything. No transparency is like saying fugg you to all investors.
