On the tax return a few simple question:

Q1. Do you consent to having your tax details released to the public? Yes No

If they refuse to let their details be released then don't release them. I know people want to see what the famous people earn, but if famous people need to reveal their earnings, then why not ordinary people with low incomes?

BTW, I think the court was right, if the info is release by the government, it is just journalism to report it. The problem is the government releasing people private tax information.

It's only a problem if the people of Finnland think it is, they've decided as a society that the information should be available. I agree with them and it appears you don't.
