Most interesting part, imo:

"Today's decision doesn't have any direct legal effect. It simply finds that Estonia's laws on site liability aren't incompatible with the ECHR. It doesn't directly require any change in national or EU law. Indirectly, however, it may be influential in further development of the law in a way which undermines freedom of expression. As a decision of the Grand Chamber of the ECHR it will be given weight by other courts and by legislative bodies."

So yeah, this is a precedent for other cases. This decision could bring forth bad things, but the decision doesn't really have any effect right now.
