Unfortunately on mobile the zoom is fixed (I can't zoom out, didn't know that was possible) and I can't see the left and right edges of the text.

I hate when they do that. Here is a bookmarklet that will fix those pages:

    javascript:document.querySelector('meta[name=viewport]').setAttribute('content','width=device-width,initial-scale=1.0,maximum-scale=10.0,user-scalable=1');

The real fix is of course to complain to the page author.

Reader mode on Firefox does a great job too!

Reader mode in Safari on iOS works great as well, but the zoom level doesn't seem to be fixed, either. It's initially zoomed in but I'm able to zoom out and it will stay.

Checking the desktop site checkbox on Android chrome fixed that for me.

Settings > Accessibility > Force Enable Zoom; it's one of the first things I always enable.

Why would anyone want to restrict the reader in this way?

Incompetence.
