At least in the case I remember it wasn’t a bot network. They would just put them on popular playlists so it’d end up with tons of listens. They were basically fake bands created as a way to get around paying licensing fees. If there’s no real band there’s no royalties to pay.
It doesn’t have traffic data, which is probably the biggest disadvantage. The maps are user contributed, so the quality varies widely. Depending on where you are, it’ll be ridiculously detailed with individual bushes in a park, or it’s incorrect or outdated and you can’t find your destination. I usually use this or OSMand, but I still keep google maps on another profile as a backup.
