Logitech mice and keyboards have extra features that the OS would consider non-standard; you can customize a lot of behaviors as well as map extra buttons to specific actions. For some reason, Logitech decided not to store customization settings on-device so there is a background daemon that must run on the host. Also inexplicably, it is an electron app with a 600MB install footprint requiring online connectivity (apparently there's also an offline version, weighing in at 1.2GB). Also not available on Linux.

No need to be modest! You can explain it!
