Misskey/Sharkey are Mastodon but with added or tweaked functionality, Misskey is directly forked from Mastodon iirc

Better then just replacing the ECU, make it open source

No clue on the data sharing regulations but your linked source does nothing to disprove the claim? The (very oddly written) article does not link out to any research and has no actual data within it other then saying truckers are 11times more likely to crash in a sim if they are tired and distracted

A lot of people overblowing this in the replies right now. Machine-id is mainly used by fleet admins at companys to manage individual devices, to generate system application keys, or tag logs (and yes systemD provides this file, but so does dbus and many non systemD applications depend on it). Chrome and Firefox might access your machine-id but their also tracking you in much worse ways by default aswell, if you care about privacy your probably already using an alternative browser that dosent use your machine-id

The problem isnt windows or linux having a machine-id but that your applications are not properally sandboxed (flatpak does not sandbox /etc by default, so no, flatpak is not a solution) or that your using applications that handle security poorly

Personally I use pure wireguard, but it was a nightmare to setup when your working overtime (in the USA). Sometimes people need a simple binary that just connects without any further research, but I will admit now that I know wireguard it feels incredibly simple
