That's a bit of a jump isn't it? Firstly, the CTs allow you to
change the license without any regard to preserving the attribution
clause.
If they do, and if attribution is ever removed, data contributed under
an agreement to maintain attribution couldn't be used.
So a future evil OSM couldn't suddenly start publishing OS materials
without attribution.
But your missing the point. The since the CT's allow the possibility in the
future that data might be published without attribution, then its impossible
to contribute data (and still be acting in accordance with the CT's) which
absolutely requires that attribution.
If you want to propose a rewrite of the CT's which has wording which
guarantees that any data which requires attribution will be removed, and
find a way of making sure any data submitted which requires attribution is
somehow marked in perpetuity so it can be identified, then I guess it might
help with this issue.

Secondly, the ODbL doesn't require attribution to Ordnance Survey,
only to OSM. Thirdly I'm not yet convinced that ODbL's attribution
ODbL 4.2.c requires that the copyright notices be maintained when
distributing the database. This would include the attribution required by
OS.
ODbL 4.3 requires a notice on Produced Works that mentions the source of
the data through a url. The page linked to by the url can mention
attribution. BY allows this, and OS data is explicitly declared to be BY
compatible.
An OSM map on a postcard under BY-SA 3.0 derived from ODbL data will
advertise OS data just as much as an OSM map on a postcard under BY-SA
3.0 derived from BY-SA data will. Both will carry a mention of the
licence and a url that links to a page explains the licence and
attribution for the tile.
is viral. A sublicensee of a Produced Work has no obligations that I
can see.
It will be the practical upshot of just about any licencing of a produced
work I can think of but I agree that it does not appear to be mandated.
I'll ask odc-discuss.
