At least some posts referenced are pretty bad, some are reasonable...

This article explains the motivation of the pattern and its misuse, which happens when applied in cases unrelated to remote APIs.

hmmm... and what pattern do you suggest??

I don't know the detail of your requirements. Patterns are not just used or not. They are matched to some architectural development and then used or not, or adopted, or modified, or new patterns are created... It should be driven be the project, not by the pattern. Patterns are just created and shared by the authors of successful products and universally valuable decisions drawn from them, to make development of architectures easier. It's not that a pattern is part of the project's goals.

In your case, if you are using or creating remote APIs, DTO can be useful, or maybe not, but outside of remote APIs, certainly set it aside. Outside of this scope, the whole approach is wrong. Again, using a pattern, any pattern at all, is not one of your goals. Main tool here is your brain. In my view, this is how it looks. After you analyze some goals and/or problems, you start thinking, "shall I apply some regular systematic approach, some pattern, to be implemented on some universal layer of the product?". Then you might start devising such pattern (or not). And only then, you just look around, and ask yourself, "did other people already created something similar?". And only after you do all that, you start considering existing patterns. Or not.
