For those concerned about contributing to Mapillary specifically, there are alternatives to contribute to, like Panoramax, which is fully open source and supports federated instances, and is not owned by Meta.
(Panoramax integrates with iD and JOSM just Lille Mapillary.)
Panoramax instances are currently only really available for France and Belgium though. Turns out it is neither easy nor cheap to host that many pictures.
