Q team, MI, POTUS, etc. are masters at psyops and human psychology. They have a far better understanding than we do of what the information they possess would cause to happen.
World war, civil war, government collapse/chaos, wide scale rioting, etc. are unacceptable outcomes. Too many [good] people would get hurt and it would allow the [bad] to disappear; thus, they must balance operations with public exposure. Eventually (much longer term), more will be revealed.
