Attribution is guaranteed by the Contributor Terms (section 4), which
continue regardless of the licence chosen.

In addition, the latest version of the CTs (1.2.3, at
only requires of the mapper that you grant rights "to the extent that you
are able to do so".

So you do not have to grant rights over OS data that you do not have. You
are only asked (Section 1a) to ensure that "You have the right to authorize
OSMF to use and distribute those Contents under our _current_ licence terms"
(my emphasis). The Open Government Licence is compatible with ODbL, so
contributions derived from OS OpenData are fine. Withdrawing incompatible
data after a putative future licence change is OSMF's problem, not yours.
