[21:02] While the GDPR aims to regulate the use of personal data, Richard Stallman proposes a law to stop collection of unnecessarry data altogether. He's right about that.
In this context I'd like to point you to paragraph 3a of the german federal data protection act:
"Die Erhebung, Verarbeitung und Nutzung personenbezogener Daten und die Auswahl und Gestaltung von Datenverarbeitungssystemen sind an dem Ziel auszurichten, so wenig personenbezogene Daten wie möglich zu erheben, zu verarbeiten oder zu nutzen."
("Personal data are to be collected, processed and used, and processing systems are to be designed in accordance with the aim of collecting, processing and using as little personal data as possible.", full translation here)
This concept is named "Datensparsamkeit", which roughly translates to "data avoidance", "data minimization" or "data reduction". So, german law actually requires what RMS proposes. (YMMV, though ...)
Personally, I refuse to add trackers like Piwik or Google Analytics here and on my actual personal website. Also I wont add external scripts, fonts et cetera, which I also consider trackers. Datensparsamkeit seems like a good idea.
