There are two different things being discussed here, and it's creating a disconnect.
The first is, "Can autistic people admit they are wrong when they themselves know deep down that they are?"
The second is, "Can autistic people be easily convinced that they are wrong?"
I'd say most commenters are expressing a "no" to #2, but your replies retreat to #1. I.e. you say that once you know you are wrong, you find it easy to admit it. However, given the content of your article, I'd speculate that it is very difficult to actually convince you that you are wrong in the first place.
What I expected: an article about the common ways in which autistic people don't realize they're wrong and therefore refuse to admit it. For example, autistic people will often optimize their engineering decisions around a performance metric (speed, memory usage, etc) that doesn't matter much, rather than a business metric (ease of use, maintainability) that does. When you push back, they will accuse you of not valuing "good engineering", just like this author does.
What I got: an article lecturing neurotypicals about how, whenever they think an autistic person may be wrong, it's actually just because autistic people are more holistic thinkers and know more than them.
