Actually the page is not wrong. The metadata uses
[[info.guardianproject.orfox]] which then gets expanded by the
client/the web repo to whatever it thinks the correct app info page
is. If you use the F-Droid client and have mainline and guardian repos
enabled (which they are by default), clicking on the link will
navigate to the correct Orfox page.
Btw, no need to post to both, forum and issue tracker.
I first filed the issue here before I discovered the bug tracker. Sorry.
