Actually there is a missing alternative to Mapbox, Google Places and Geocode Earth. As they explain it this blog post, Algolia Places relies on OSM Open Source community to maintain accurate data. Since it's not anymore a business for Algolia, they could Open Source their software (API, user-agents and tooling) and let an Open Source community maintain the software. Not only the data from OSM.
It would be a nice sign from Algolia towards their customers.
