Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

That's a pretty big jump that the article makes... Here's what the decision is about:

The Court, sitting as the Full Court, holds that the general and indiscriminate retention of IP addresses does not necessarily constitute a serious interference with fundamental rights

They also said that, which is true:

EU law does not preclude national legislation authorising the competent public authority, for the sole purpose of identifying the person suspected of having committed a criminal offence, to access the civil identity data associated with an IP address

I should point out that copyright infringement is not a criminal offense, it's a civil matter.

None of this adds up to what the article claims.
