There are people who might access the web with screenreaders and other affordances who also suffer broken experience due to js religious like adherence. Should we tell them sorry, the internet is for the able bodied, or do we make affordances for the disabled like we do in the physical world?
It is about accessibility, though not necessarily screen-readers. I live in a rural area and, aside from the tracking shit they cram in, mountains of Javascript (and CSS) materially affect my ability to connect, browse and communicate. Accessibility is also about where you live, and we don't all live in cities.
As a side note: What happened to printing in web browsers in the last 10 years. They are all horrible at printing.
