Changing your oil at 1,200 miles is not only wasteful, it is doing a disservice to your engine by draining out any break in compounds the factory deliberately adds to the oil at the time of assembly. Regarding any theoretical "wear metals", do you honestly think they get circulated through your engine? Honestly, it doesn't work that way, there is this thing called an oil filter which takes care of said metals, if in fact they do exist.

Any reference or cite for "break in compounds" in the factory oil?

Yes, the wear metals circulate in the oil. This is fact, not up for debate. With the oil analysis to prove it.
Prior to moving into AI, I worked as an engineer for three of the world's auto makers, you don't need to believe me, I mean, I'm just some schmuck on the internet, but hey, so too is the video. As for wear metals circulating in the oil, no, oil analysis does not prove it; what oil analysis shows is what is in the oil pan; the only way oil analysis could "prove" the metals circulate is if you can take an oil sample downstream of the filter. That said, it is true micronsized particles do circulate, but they are far too small to do any harm to the engine.

As for if wear metals do exist: if they didn't exist then an oil analysis could not find them.
Bad logic on your part. The wear metals settle in the bottom of the pan where they are drained out at an oil change; most never get picked up by the pump strainer, and if they do get picked up, they are either, A) filtered out or, B) too microscopic to do any harm to the engine.

All of the issues mentioned (Tundra engine specifically) are due to manufacturer mistakes and not because someone did or did not change their factory oil at a specific interval. Just don't exceed 7500 in between oil changes and any new vehicle that doesn't have manufacturing flaws will be just fine.
But by all means continue arguing on an internet forum... guys have been arguing about oil since being online was a thing.
At least there is activity in Smorgasbord.
Manufacturers don't care anymore about the longevity of their products beyond a comfortable margin past warranty expiration (if we are lucky they shoot for "after"). We are decades past that pride, and seem to be firmly in a throw-away society.
Any new machine, change your break-in oil after break-in.
And some machines, depending on the origins, drain out that crap excuse for oil and refill with quality before 1st start-up.
As for 7,500 mile oil changes, I call hogwash and always have.
I have also always called hogwash on "oil time interval" (I.E. X miles, and/or every 6 to 12 months) Complete marlarky. Oil doesn't have a 1,2,3 year expiration date.
Do as you will, but since I keep my vehicles until end of life, there is no way I go past 5,000 at a maximum. You can feel an engine slugging on 6,000+ mile oil. Some engines you can feel it slugging on 3,000-4,000 mile oil.
Agreed, you do you; my last car, a 2006 Acura TL 6MT had over 220,000 miles on it when I traded it in on my Tacoma; at that point it still was not using even a half a quart of oil between oil changes, and I rarely changed the oil before 10,000 miles. Over the years I've had five vehicles ranging from small compacts to large(ish) minivans, all made it past the 200,000 mile threshold, and none of then ever used oil.
