I just saw that Mozilla is retiring Mozilla Location Services which provided an open, crowdsourced alternative to proprietary location services from Google and other vendors. 😰

This is used by GNOME and thus Fedora, Ubuntu, Endless OS, etc. to help provide OS-level location services without requiring every app to implement its own. And apparently a patent troll is part of the reason Mozilla stopped investing in it. 🙃
