The question we need to be asking is: What are Groundspeak going to do about improving the quality of the current mapping?
Yes, since Groundspeak dropped Google maps, the alternative has been vastly inferior to what we've been use to. We've even lost aerial/satelite imagery.
With regards to the normal mapping, we also have the option for OSM rather than MapQuest, (which is what I use most of the time). Cachers could also improve OSM maps by adding and editing the tracks from their GPSs to the OSM system as they would most likely be following footpaths and bridleways, (in the UK).
Another thought: Do Bing charge for there map content usage like Google do now? If not, why aren't we using that platform?
