Can I link to fiwp of the same page? Capitalisation "CC by SA" makes no sense, both should be equivalent.
- License abbreviation fixed in gerrit:37677.
- Yes, you can change the URL to a translated version of CC BY-SA 3.0, but you cannot make it a country specific license version.
CC should have translations of these, why does it link to Wikipedia?
I don't know, it was decided by the WMF legal department. In more than a year of discussion we've not managed to make any sense out of it, so just leave the English source alone and make correct translations (pointing to CC).
That's bad. Translators a scolded if they customize instead of translating.
I didn't get scolded last time, the WMF should. WMF bureaucracy is impossible to overcome, so at some point they have to be worked around. A year of attempts at using the correct process is well enough.
Or, to be slightly less aggressive, you were told by WMF legal that it was OK to link to the Creative-Commons hosted version. :-) The fact that the English Wikipedia decided to have a locally-hosted copy of their licences should not drive your decisions. Yes, ideally enwiki would be the specialised message and the core message would be otherwise, but it's a minor issue.
