I dumped 11 popular Google apps on my Android phone for these open-source alternatives.

I dont understand the need for Quickshare/LocalSend. I rarely send files directly to a person near me - though I have occasionally shared a file via NextCloud but it was usually for someone across the net. If its small, like a picture, then its just Signal. And KDE Connect is excellent for sending files between my devices.
Am I missing another use case?
