I mean Stoner designed the gun to never be cleaned, are any of you operating your rifle like that
*Sigh*

Now this one, at 15:25 into it the man himself expresses his incredulity that the M16 was issued without a cleaning kit.

What you have to put into context is the politics and procurement of the time. WW2 just ended, officers and generals came from that time. They were used to 30 caliber, wood and steel. Every branch of the armed services procured it's own firearms to different standards.
Enter Robert McNamera. Harvard MBA. He served in WW2 in the office of statistical control. He analyzed efficiency and effectiveness of bombing runs. Eventually he becomes the CEO of Ford Motor Company. He then is tapped to serve as Secretary of Defense under Kennedy and Johnson.
You get a progressive administration embracing the "space age" and emerging computing technology. You add in a Secretary of Defense that comes from the business world that wants to streamline the DoD procurement process to be more financially efficient. You have a guy and his "whiz kid" team who run things by the numbers.
You have two philosophically opposed groups going at each other. Both were right, both were wrong.
McNamera and his team ran by spreadsheet. .223 ammunition is less expensive to produce than 30 caliber. Soldiers can carry more rounds. More rounds = more chances at killing enemies. Their error was in trying to make the rifle as inexpensive as possible, against Eugene Stoner's design.
- No Chrome Line Bore
- Ball powder instead of cleaner stick powder
- It's space age! No need to clean it. No need to spend extra on cleaning supplies and training.
Rifles jamming? Well let's just add a forward assist, no need to clean.
The old military establishment wanted the rifle to fail, they wanted the procurement process that McNamera mandated to fail. I'm willing to bet that military leaders didn't speak up as all of the changes go against firearms common sense.
All of this and more went into the design evolution of the M16/AR15. It wasn't just a Eugene Stoner design. The political and military industrial complex of the day had as much sway into what got issued.
