Someone on a German forum made a wider version of it which (imo) looks much better [1].

I don't know of a way to heavier outline fonts. I believe the commonly used versions aren't in fact derived smoothly from Metafont, but either fitted to the bitmaps, or drawn by hand over them. That would have been a good time to correct this sad mistake.
Related: the serif font Equity comes in two grades to compensate for such types of printers (though both grades are thicker than Computer Modern), and discusses the rationale for this feature: https://mbtype.com/pdf/equity-type-specimen.pdf#page=5

As I recall, there were occasional other issues with running MF on the CM sources at low resolutions and it was often necessary to just tell MF to continue at the error prompt to generate the font (when Tom Rokicki's dvips incorporated auto-running MF to generate missing PK files for specific resolutions, I think it ran it with a default setting of ignoring errors).
Those 1980s Xerox laser printers were real beasts. The 87xx/97xx series printers were prone to rolling over (crashing) on TeX print jobs since downloading fonts to the printer was not fully supported. The first dvi driver for the Xerox printers actually required pre-installing font sets on the printer and only certain combinations of fonts could appear in a single document. I don't think the 27xx series printers were ever capable of handling TeX output.
Sadly, mobile Firefox does not support that, so HN on Android is relentlessly sans.

I never got the "Linux Libertine O" fonts to work in my phone. I suspect it doesn't like the file format.
However, there is a part of the curve where random failed grad student and retired professors become conspiracy cranks and email you half-baked theories about the shape of the universe, typeset in Latex -- and those get through the filter unfortunately.
I can see why some people like it since it's the default font for a lot of technical documents and seeing it often signifies a certain level of "quality". The documents generally look better than Word documents, for example. Moreover, if an author took the time to learn LaTeX, it is easy to assume that they know what they are talking about. This is a form of "honor by association" (opposite of guilt by association fallacy).
Relevant XKCD:
> Anything that relies on something other than TeX or (PDF)LaTeX will fail. At this time arXiv does not support processing with: XeTeX and its variants including LuaTeX, LyX, or PDFTeX. [0]
However, you'll frequently see papers with:
> Comments: PDF file generated using XeLaTeX/XeTeX.
Such as [1], where the author would prefer submitting a PDF-only than jump through the hoops to make it work under standard LaTeX.
It's the default font in Beamer, and I find when I make it the default font for non-serious publications, it looks really clean and modern. I especially like its rounded edges -- makes it look Web 2.0ish.
