passim

looking at the fwupmgr code. The client uses DBUS to ask the server how many bytes were download from your LAN peers (unless you connect your device directly to the internet, then i guess i will show how many bytes ssh probes downloaded from you, inflating their numbers and making them more aggressive on the server feature) https://github.com/hughsie/passim/blob/ae38c13da1a63fff8c8fa... https://github.com/hughsie/passim/blob/ae38c13da1a63fff8c8fa... also, note the quaint code to tell how much carbon it saved earth. edit: interestingly, if you search for that data collection method name, both ddg and google only find the call from fwmgr side. the actual one, older, from passim code is not shown anywhere https://duckduckgo.com/?q="passim_client_get_download_saving... but it's there https://github.com/hughsie/passim/blob/ae38c13da1a63fff8c8f
