This makes it a bit trickier, yeah, though if the developer can get an APK signed with their Play App Signing key, and the app in question is a reproducible build, they can then publish it in F-Droid: https://fdroid.gitlab.io/jekyll-fdroid/docs/Reproducible_Builds/#publishing-apks-with-the-upstream-developers-signature https://fdroid.gitlab.io/jekyll-fdroid/docs/Reproducible_Bui... (and probably they can upload it to their GitHub releases or something so that F-Droid picks it up from there)
