It's 2022 and in spite of the often-praised superiority of LaTeX, we are still getting paginated PDFs on ArXiv, instead of responsive text that reflows on different screen sizes. PDFs were great to read when I was still printing papers. For reading on screen they are quite inconvenient. Many publishers have come around in…
It's not about LaTeX per se. You can typeset EPUBs with it too, if you want. So reflow ability is not a shortcoming of LaTeX.
Publishers send you a Word or LaTeX template, and require your manuscript as a PDF, conforming to that template. If it's LaTeX, generally there's a switch to render the text in "Review mode" with line numbers and similar additional details, and omitting author data if the judgement will be done blindly.
So, the tool itself, regardless of its brand is the proverbial wrong tree to fight with. Also, it's a reality that reading a 25 page manuscript is not very efficient on a screen, at least in my discipline. I have a dedicated "Paper printer" at home for printing such manuscripts and taking a stab at it with pens and highlighters.
