I think there was a clique within the conspiracy that felt it was time to roll out the heliocentrism deception, and another that felt the time was not yet ripe. Galileo was only slapped down for jumping the gun.
When the Inquisition decided to "slap you down" it was a bit more serious than a fine and some points on your driver's license. All those religious fanatics are roasting in hell, and will do so forever. If not then there's no justice.
