No, amMap provides their maps free even for commercial use. The only limit to the free one is the small link displayed inside the map back to amMap.
No purchase necessary.
I have found that it will leave your settings in the database on deactivation but when you activate it again it won’t update the map.
One fix is to simply edit one of your countries in settings and then click update. That will fix it so the map updates again.
I’ve modified this one to cover the USA. I’m planning on posting it soon.
I don’t know about adding a flashplayer warning, but I’ll look into it.
