App installed from F-Droid and updated via Playstore? (feddit.de)

I have installed Davx5 from F-Droid, from IzzyOnDroid Repo. Today I have checked for updates with the Google playstore and the App was updated to the playstore variant. I thought this isn't possible? What's going on here?

The apps on IzzyOnDroid are built by the original developers and likely signed with the same key as the version on Google Play. As a result, Google is able to update them. Apps in the official F-Droid repository are signed by F-Droid. As a result, the keys are different and won't be updated by the version from Google.

It can also happen with apps from the main repo. If the app is reproducible (about 5% so far, most new apps) then F-Droid will use the developer signature.

This makes sense. Yes, I have paid in the playstore for this app (and I would do it again and again). But if I understand it correctly this would also mean, I could download their v4.3.8-ose from the official GitHub repo for free, and it would be updated automatically from Playstore to v4.3.8-gplay version (which is not free). Strange.

But this app is worth every penny.
