The primary purpose of those buttons is of course to let those sites track everyone’s browsing activity across every site that uses them, which does not require that anyone ever click on them.
Even if less than 0.0001% of people click them, anyone with an SEO/spammer “grindset” will assure site operators that the potential benefit of someone sharing a link they otherwise wouldn’t have is still at least theoretically non-zero. And, since there is absolutely no cost at all besides an acceptable number of extra milliseconds per pageload, really, it would be downright irresponsible not to have them there!
I don’t use it, but,
sudoeditis a little more complicated than that.details

man sudo:When invoked as sudoedit, the -e option (described below), is implied.-e, --edit Edit one or more files instead of running a command. In lieu of a path name, the string "sudoedit" is used when consulting the security policy. If the user is authorized by the policy, the following steps are taken: 1. Temporary copies are made of the files to be edited with the owner set to the invoking user. 2. The editor specified by the policy is run to edit the tem‐ porary files. The sudoers policy uses the SUDO_EDITOR, VISUAL and EDITOR environment variables (in that order). If none of SUDO_EDITOR, VISUAL or EDITOR are set, the first program listed in the editor sudoers(5) option is used. 3. If they have been modified, the temporary files are copied back to their original location and the temporary versions are removed. To help prevent the editing of unauthorized files, the follow‐ ing restrictions are enforced unless explicitly allowed by the security policy: • Symbolic links may not be edited (version 1.8.15 and higher). • Symbolic links along the path to be edited are not followed when the parent directory is writable by the invoking user unless that user is root (version 1.8.16 and higher). • Files located in a directory that is writable by the invok‐ ing user may not be edited unless that user is root (ver‐ sion 1.8.16 and higher). Users are never allowed to edit device special files. If the specified file does not exist, it will be created. Un‐ like most commands run by sudo, the editor is run with the in‐ voking user's environment unmodified. If the temporary file becomes empty after editing, the user will be prompted before it is installed. If, for some reason, sudo is unable to update a file with its edited version, the user will receive a warning and the edited copy will remain in a temporary file.tldr: it makes a copy of the file-to-be-edited in a temp directory, owned by you, and then runs your
$EDITORas your normal user (so, with your normal editor config)note that sudo also includes a similar command which is specifically for editing
/etc/sudoers, calledvisudo🤪
