The €10m fine tells you they did not sympathise too much with City on that issue.
They must have been reasonably sympathetic to cut UEFA's €30m fine for not cooperating down to €10m.
Also if they thought the non-cooperation was as serious as the breaches (which I think they would if the idea that the obstruction is what stopped UEFA proving their case had merit) they could have kept the ban for obstruction or made it 1 year, couldn't they?
