Don't make assumptions about me. A LaTeX document is also virtually never directly consumed by web browsers.
In addition to that we are considering LaTeX for the web, not DVI, not PDF, not something else that you compile LaTeX into.
And well, given the amount of people that use overleaf I would say that a lot of people (although writers instead of readers) consume LaTeX.
(Btw, you can compile html too, try printing it as ps/pdf document)
