A long time ago, I was a math T.A. in the university and the main T.A. of my course was blind. He used a screen reader for everything, and wrote LaTeX and had a paper versions of the courser exercises in Braile+LaTeX (IIRC).
> a PDF alternative for the blind
I'm not sure what it means. It's a PDF reader? It's another format that is similar PDF but more screen reader friendly?
> Google Maps/navigation for the blind in my city
Do you know https://www.openstreetmap.org/ The data is open, so it may be useful to build an easier to use client, so you don't have to collect all the info.
> I am concerned about parasitic big corporations taking the code and putting it behind a paywall
Probably AGPL is better for your intentions.
> Not only would I be inviting disorganized, poorly constructed code,
There is no obligation as a maintainer to merge all PR. But remember to be nice.
