Pricing changes are a real issue. Google maps spiked in cost and those who were using leaflet JS just had to change a few settings to switch to another provider. Those who built using googles map js are locked in.
Yeah...We had a fixed yearly price for Google Maps API Premium account - when they switched us to PAYG, our costs increased 8x...Spent 2 weeks of unplanned urgent work switching to Mapbox for 3x of original cost...
