I will be eventually replacing Google Maps with something else. Same reason. Googles credit card requirement which i refuse to do.
I realize most alternatives don't work well in all areas, but we also don't know if Google Maps is accurate for every country either.
However, the existing google maps module will be retained for download and hopefully a third party developer will be interested in taking over maintaining the google maps module. And perhaps other developers will do even more map alternatives.
Thats the great thing about modules vs built in features. Things can be replaced when using modules to suit your own needs or area.
