I would understand if the clock was connecting to a dedicated service to sync the time, but the clock app is just an interface where I can set alarms, use stopwatch etc. The system time is managed (and synced) at the Android OS level and so there is no need for apps to connect to the internet, nor for it to have updates.

For the finder app, the index should be local. There is no way I want my apps, documents and file metadata to be sent to some samsung server to be indexed so that I can do a local search -- that would provide no value and it's also features that I've never asked for as a user.

The calls from most of these apps (especially samsung apps) to facebook servers also serve no purpose other than to try and datamine. I understand there may be cases where telemetry is valuable, but it's unacceptable to have apps (in many cases that haven't been opened) to try and connect to a remote server behind the scenes, especially when you cannot remove them easily.
