Documented cause
Kazaa launched in 2001 as a peer-to-peer file sharing network, quickly becoming the most downloaded software in history with 250 million downloads. The RIAA sued Kazaa's parent company Sharman Networks in 2003. In 2006, Kazaa settled for $100M and agreed to add DRM filters. The user base collapsed as BitTorrent offered the same functionality without legal liability. Kazaa attempted a relaunch as a legitimate music subscription service that lasted until 2012.
Lesson
“Centralized infrastructure in a legally hostile environment is a settlement waiting to happen. Decentralization is a legal strategy, not just a technical one.”

FAQ
What happened to the Kazaa founders?
Niklas Zennström and Janus Friis went on to found Skype in 2003 — while Kazaa was still under RIAA attack. Skype was acquired by eBay for $2.6B in 2005, then by Microsoft for $8.5B in 2011. The founders did extremely well despite Kazaa's legal troubles.
Did the RIAA's strategy against Kazaa work?
Partially. It killed Kazaa, but BitTorrent immediately filled the void with a more decentralized protocol that resisted centralized legal attacks. Music piracy did not decrease; it migrated to a harder-to-sue infrastructure. The RIAA later shifted strategy toward suing individual users.
