You have said that CT 3 allows the data to be published without 
attribution in the future. I am saying that doing so would break CT 4.

Oh I see. I'm talking about the Ordnance Survey's BY-compatible licence 
rather than BY-SA but attribution inheritance is the issue, yes.

I'm saying that, assuming it's OK to add such data, the CTs don't say 
"and later an evil OSM(F) can strip attribution from such data". CT4 
says that attribution is a condition for *OSM*. If OSM wished to move to 
a non-attribution licence then attribution-required data could be 
removed, but it could not stripped of its attribution.
