How do you know that they stopped using Altitude Angel? I can see from the
map that they use Mapbox now, but can't they use more than one data source?

That might be your opinion, but I think a court would disagree. Courts
often look at norms in order to interpret a licence.

fact, requirements that are too strict will *discourage* the "distribution

opposite of "providing geospatial data for anybody to use and share."

Great, so now you are saying that OSM has been doing it wrong since the

"You must keep intact" means don't delete them, not, "can't be a link".
That last clause is "to the extent reasonably practicable, the Uniform
Resource Identifier, if any, that Licensor specifies to be associated with
the Work." In other words, include a link if the Licensor wants you to
include a link! No one has suggested that the attribution should be only
