Questions about Lite, mainly Ubuntu privacy oriented

[bitsnpcs]

Hello newtolite,

I am only beginner level of user, LL is the first distro I have installed, and can say just this -

A: #1 - Linux Lite has its own repositories, as it is heavily modified, this is beyond my user level to understand at this time, someone advance will answer about it hopefully, these are used in addition to upstream Ubuntu repositories.
LL at user end also visibly has -
Install Updates (from both repositories)
Lite Software
Lite Tweaks
Lite Updates Notify
Lite User Manager
Lite Upgrade
Lite Welcome
Support (forums)
Lite Manual

The default installed softwares, are carefully selected, often with community input, from the wallpapers, icons, to the software chosen for default install, and also the software in Lite Software.
In addition it has community made start up sound, wallpapers.

A:#2 - Linux Lite is not use Unity desktop, it use XFCE desktop, Ubuntu is also stopping using Unity desktop in near future, unsure about the Amazon links.
Linux Lite has no commercial links embedded on the menu, or desktop that I have seen.
