Hey infeeeee, it looks to me like you think you got personally attacked. mcliquid simply asked a question and you seem to answer somewhat hostile, unfortunately :(

This is a community project and the project lives through questions as well. 

If you used https://ec.europa.eu/eurostat/web/gisco/geodata/reference-data/administrative-units-statistical-units as base it it clearly should not be used. The ODbL directly violates their 2.1 clearly because ODbL allows the commercial use of OSM-Data. 

So the correct answer to that is not to be hostile against the person asking but to try to find a better source or to explain why its still valid or simply ask eurostat if they make a special permission for OSM. 

This should probably more widely discussed in the forum, but lets wait for the DWG first now they are contacted already :)
