IMO it's clear that the current OS license does not allow you to
contribute the data under either the current OSM Contributor Terms, or
the DbCL part of the license. (I'd also argue that the produced works
terms in ODbL are incompatible with the OS license too, but that's
less clear.)

What isn't clear yet is whether either side will be prepared to
compromise to allow information derived from OS OpenData products to
be kept in OSM.

I am hopeful that OS will allow use under ODbL+DbCL, but I personally
can't see them agreeing to any contributor terms that don't guarantee
