>It's not great, but you can't expect people to fix everything, especially for fairly minor issues like this.
1. It's not a minor issue that a privacy feature doesn't work.
2. OP clearly stated ( https://gitlab.gnome.org/GNOME/evolution/-/issues/3095#note_... ) that they know the fixes are not trivial, so at the very least they want the application and website to make it clear that the privacy feature doesn't work, so that users are not misled.
