The only feedback I get when installing d-spy is "Uses System Services", and "Uses Session Services", which means nothing to me as a user, and yet it allows program to enumerate all programs I use and as it turns out even hack my computer. Other platforms solved this with something like "developer mode", iOS, Android, Meta, etc. I shouldn't be able to install this app without confirming developer-mode-only permissions. As for this particular app it is offline, yes, but dbus allows for cross-app communication, so no more
You’re running desktop Linux - your whole system is permanently in “developer mode”. That’s kind of the point? Windows and macOS don’t have “developer mode” either, at least not to the extent seen in the mobile OSes.
