I agree with you, but I go one step further: I am disappointed by OSM raster tiles and especially Google's digital tiles because even they show barely enough information, if you compare them to old style printed street directories. I think they also have a tendency to avoid crowding by omitting important things in busy spaces and showing useless things in empty spaces, whereas the correct thing to do is to show the important things in the busy spaces precisely to indicate that they're busy spaces. And I think there are better things that can be done than just showing trivia if you consider the local area (e.g. a private tennis court might be better off not shown in especially if there's not a great density of mapped objects, but perhaps it's relevant at a resort).

But that's a lot of work, and whereas it's easy to add extra trivia to OSM it's much harder to add extra detail to tiles.

As Doctor_Fegg has pointed out further down, the OSMF provided raster tile service on openstreetmap.org is primarily intended to provide fast feedback to contributors and not for general purpose use, in particular not as a competitor to google.

The whole point of OSM is that you can take the data and build / design your own things. Yes it would be nice if there were multiple viable google alternatives based on OSM and other open data, but that is likely just a pipe dream, the economics don't really work.
