Hi Marc,
Thanks for reaching out to us!
For people who don’t want Google Maps on their website, there is the option to not display the map or the map link in the event editor, so it will display the venue’s address and nothing else on the single event page and archive views.
But offering the possibility to choose another Maps provider would be a very nice addition! A user already suggested a similar idea on our Feature Ideas forum.
I invite you to vote for this idea, as the features getting the most votes will definitely be on our radar.
Have a great weekend,
Jeremy
