I wonder what makes you feel that. I've been publishing preprints close to a decade on arxiv now and never had any particular feelings about it.
To me it's just a way to get out your work fast, so that there is already a trace of it on the Internets - nothing more and nothing less.

Isn't that normal with highly specialized research fields? I agree many papers could benefit from clearer wording, but working in a niche means you sometimes don't reach a broader audience
It's an opinion, and you feeling no particular way about it is equally valid.
But I did justify and maybe to reword slightly, surely if one of the main drivers is opening up research, the brand name should be something that's less obscure and more accessible / understandable as to what it is on first sight?
Maybe arXiv evoking the word 'archive' with an ancient Greek twist does that for some, but it's clearly a bit cryptic for many, and if the point is to open up probably the brand should just be something much plainer.
