Word and PDF also support semantics readable by assistive technologies. With a LaTeX file, the user has to go through the raw code, often character by character.
Yes, but I was responding to a post that wasn't about "most people." For people who use a screen reader because they have a visual impairment, a PDF is better than a raw LaTeX file if the PDF has been produced in a way that includes document semantics. My understanding is PDFs produced by LaTeX converters do not include such semantics, the code is only meant for printers, so also having the raw LaTeX file available is better than not having it.
