This is really good, and very much in accordance with both the text of the
ODbL and the long-standing precedents set by the osm.org/copyright page.
Thank you.

Two small wording clarifications:

"If OpenStreetMap data accounts for a minority (less than 50%) part of the
visible map rendering, attribution with other sources on a separate page
that is visible after user interaction is acceptable."

This probably needs to be qualified to the "currently visible map
rendering", and "50%" phrased as "50% of objects" or similar - just to
clarify the (quite likely) scenario where a map uses OSM data in (say)
Turkey, TomTom everywhere else, and Natural Earth for coastlines/land.

"It is permissible to use a mechanism to collapse the attribution as long as
it is initially fully visible"

This would be better as "It is permissible to provide a user-activated
mechanism to...". There are apps which flash up an OSM credit for under a
second, after which it disappears (including one terrific iOS mapping app
which I would otherwise recommend).
