If thin oils are bad then Toyota is stupid?

Then you missed and entire decade-plus discussion about CAFE oils. There is a TON of evidence that mfg's went to CAFE oils, with the intention of not thinning them down too much as to cause warranty issues. Many of the same mfg's also state thicker oils can be used for heavy duty-performance-towing type applications. Same mfg's have also speced thicker oils all over the globe...except the USA.
The problem is that we don't have the research. I'd also be inclined to prefer thicker oils, but it's an opinion. I haven't done any scientific research on oil to definitively say that 0w8 is a bad idea. Even saying that I use Mobil 1 0w40 on everything. I've used it in 5w20 Fords. My current GTI is the only car that I own that Mobil 1 0w40 carries the certification for and I've used the oil for 20 years.

My lawn equipment ends up with 10w30 PYB, so I can't say M1 0w40 in everything for full transparency.

But feel free to wilfully ignore it all if you like.

It's because in the USA they just want to get past the warranty period.

In the rest of the world they want the car to last.

Yeah that’s the proof I was looking for.

You got me there.
 
That was not my intention, I just try to help people see the truth about all things of interest. Many things I do not comment on because I just don't know. Its a good discussion. Thanks my friend.
 
Toyota is known for good if boring cars that last.
People don't buy Camrys for their entertaining driving.
They buy them for the lack of entertainment in the ownership experience.
Toyota already knows this and would not recommend a grade of oil that would imperil their rather agricultural engine going well past 200K with no issues.

Toyota once had a sludge in their engines with recommended 10k oil changes, they reverted them back to 5k. They are far from being perfect when they are making “recommendations”
