The WRSTC standards for the Open Water diver say:
"Open water certification qualifies a certified diver to procure air, equipment, and other services and engage in recreational open water diving without supervision. It is the intent of this standard that certified open water divers shall have received training in the fundamentals of 4 recreational diving from an instructor (see definition). A certified open water diver is qualified to apply the knowledge and skills outlined in this standard to plan, conduct, and log open-water, no-required decompression dives when properly equipped, and accompanied by another certified diver."
You are quite correct in criticising many instructors, you are a bit misleading in criticizing PADI for its standards, but you are arguably unfair in criticizing the WRSTC standards.
