It would be interesting to federate trail condition information, since that's the true value-add of a service like AllTrails.

What springs to mind is the use of Mastodon handles for contributing trail info and discussion of information being contributed.

The only major hang-up is balancing privacy and trustworthiness of the information being contributed.

Perhaps an open solution like this will emerge as people grow tired of profit-driven services like Strava, AllTrails, TrailForks, etc.

I agree. However, I have not found a reliable, free data source yet. Do you have recommendations?

At least here in Europe, surface type and quality is available for the majority of trails in OpenStreetMap

That's true, I understood his comment more like he wants automatic updates about how well-maintained a specific trail is.
