Any claims that F-Droid will ban, censor, etc. are wrong and based on misunderstandings. F-Droid will never block the ability to subscribe to any repo that the user wants to, or to install any app from all the included repos. So the user will always be able to get secure access to any software they want to use via any network or even thumb drives:

The main f-droid.org repo is a contributor-curated collection of apps, just like every other F-Droid repo, so it will never include every single app. This is not censorship, this is curation.
