If you stop the subscription the tours will stop working also, we will not delete them just deactivate them, in case you want to subscribe back. But if you do not want to be locked in a subscription model we do have per year per tour or you can download the virtual tour and host it yourself (for a $10 fee per tour)
@stéphane-de-greef The moderator supports only Google Maps, we are using Map Box in the Tools section so we mitigate the usage cost Google Maps API has.
I understand your point. The thing is right now our focus is not on the Moderator but on the Overlay Editor, and we have no idea when we will go back on the Moderator. But when that will happen allowing you to switching between OSM and Google will be an option.
Your tour was fully map rejected, for cases like this you need to delete the tour from Google and then publish it back. Just updating does not do anything beside updating metadata for a map rejected pano. (that does not make a pano map approved)
