[Talk-GB] OSM Contributor Terms vs OS OpenData Licence

I have been wondering how much data has been imported into OSM from OS 
Opendata and who has accepted the CTs. I still think that the CTs ask 
for rights to be granted that are broader than are granted by the 
Opendata license. This point is disputed by Richard and others. Here are 
the most prolific Opendata users (in terms of version 1 objects) that 
have accepted the CTs, along with their user IDs:

9065    brianboru
41362    Eriks Zelenka
69853    Central America
51722    Chris Parker
57884    EdLoach
26825    Warofdreams
91225    tms13
592    JonS
229419    piedwagtail91
82783    Paul The Archivist

The top contributor, brianboru, has 29020 objects that use opendata 
source tags (and are version 1 objects). We should not focus too much on 
these specific individuals, as there are probably hundreds of users that 
have done the same thing. Now, if we were to accept my concern that 
Opendata and the CTs are incompatible, these users, along with users not 
listed above, are bringing OSM into disrepute, because they are not 
respecting other's license terms. The fact that they might plan to 
remove the data is in a way irrelevant, they should only agree to the 
CTs after they are in compliance.

Here is a link to a random example, from each of the above contributors:


The list of people accepting the CTs is here:


The only solution is to reject their CTs response until their edits are 
no longer in violation of the Opendata license. Unless I am mistaken in 
my interpretation of the CTs, in which case this might be a non-issue!
