TFA isn't saying "DSA is useless", it's saying "intermediate/advanced DSA is not useful for most people". It's obvious that it's useful for some people, but I think even most people working on "large scale systems" should probably value general software engineering skills over DSA skills. The very few people who actually need DSA skills already know that the advice "you don't need DSA" doesn't apply to them.

This is right. And most of those people know a lot of their job is very far removed from many other software engineers. But the prevalence of the idea "you don't really use DSA in practice" does suggest many people building applications where DSA isn't as applicable seem to misunderstand the situation. It matters in some sense - it explains why interviews at google are the way they are, why universities teach what they teach, what one should do if they really like such things.
