I feel like you didn't read the discussion at all? One of the apps does not contain any Bible verses, it is used to track which books, chapters and verses you've read.
Does it matter? F-Droid is a distributor, they're allowed to reject apps they consider controversial or outside their wheelhouse. The person who spoke up was correct, the ruling is consistent and the definition of NSFW content makes sense to me. Evangelism isn't exempted from being called and labelled as slopware.
These people can perfectly well distribute their apps without F-Droid's help, they're not refusing to sign their app or somesuch.
The consistency is that the presence of a Reddit app or a Youtube app per se doesn't reveal too much about the device owner.
A Bible reader/tracker app, a Quran learning app... now that's where you enter a more sensitive area, religious beliefs are among the higher protected classes of data under GDPR.
And now there's a few potential threat sources: family members snooping through their relative's phones, border control snooping through phones (remember, apostasy is a crime punishable by death in some Muslim countries), or the worst one, random ad SDKs pulling in and distributing lists of installed APKs and pushing these to the mothership, where the data can then be hoovered up by anyone willing to pay for it, with the same result [1].
I wish I didn't need to write this, but it's not just some random Middle East theocracy going for its citizens as usual for the crime of not believing into the god of choice, we're seeing people being threatened for their faith (or lack of it) right in the United States of America, right now.
No, there are plenty of other examples (just in games alone) to write off as a mere one-off oversight. It certainly seems targeted since they've targeted religious apps that don't even have any explicit content.
For an app store that is supposed to advocate for freedom this is disturbing and very off-putting. The answer is not submitting a PR to enable even more censorship.
These people can perfectly well distribute their apps without F-Droid's help, they're not refusing to sign their app or somesuch.
