I see no reason not to be empathetic. The frustration is fair, but it's aimed at the wrong layer. These people were guided into this spot by bootcamps and curricula that start at React and never go down the stack.

My experience was the reverse. I learned HTML and CSS first, then Rails in college to serve templated pages. I understood the client/server boundary fine as a concept, what I couldn't see was where it actually sat in a web context. I sort of knew JavaScript ran in the browser, but then I'd see ERB templates stamping values directly into script tags, so the server was writing the JavaScript that ran on the client, and my mental model fell apart. Where does my code actually execute? Why does this variable exist here but not there? Why does the page have data the network tab never fetched? Nobody ever sat me down and explained the request/response lifecycle as its own thing. I had to assemble it from fragments over years. This was around 2017 for context.

How you learn something shapes how you keep learning. If your mental model is misaligned, everything downstream is friction. The thing that finally made it click for me was reading the actual HTTP RFCs, which is apparently a weird thing to do, because HTTP itself is absent from nearly every guide and curriculum. Tutorials teach you the framework, maybe the language, and just assume the protocol underneath. These days I make newbies read the MDN docs like a book and skim the HTTP wiki page, learn the history of the protocol. It's short! It's not even a book! That gives you a firm foundation. But if your foundation starts at React, drilling down is like digging past bedrock. People don't know where to start, and Googling only shows them wrong answers because they don't yet know how to ask the question.
