Mapzen seems like a good idea, but I can't help but wonder (with respect): Can a developer expect it to be here in 2026?

Seems like someone integrating against an API has the choice of "Use one from a big company with a proven business model and risk their TOS changing to have it taken away" vs. "Use one from a firm with only a few years of history and risk them going dark one day (or changing their TOS)."

In this specific scenario, I'm not sure that this solution would guarantee the developer could have avoided this failure mode.
