Jan Philipp Albrecht was appointed as rapporteur of the European Parliament for the process of the GDPR law making. His job was to take care of the process to find compromises between many opinions and fill them into law. Since he actually cares about privacy, he was in a position to make sure that the compromises keep a certain level of privacy protection. He's from the german "green/environmental" party.
There is an interesting documentary about his role and the process: "Democracy: Im Rausch der Daten". I don't know if there is an english version. There is a german version on youtube.
The "mistake" was to appoint him as rapporteur.
The "mistake" was not repeated, when Axel Voss from the german conservative party was appointed as rapporteur for the "Directive on Copyright in the Digital Single Market (2019)".
(Note: The law making process in the EU is long and complicated and I do not know where this draft is currently in the process.)
