This is revisionist history: Netflix was legal. Craigslist was legal. eBay was legal, Youtube was legal (yes people uploaded copyrighted content, but they complied with DMCA takedowns as required to under the law)
putting DVDs in the mail was legal but when Netflix first started streaming they broke some laws.
Craigslist and ebay were "unregulated marketplaces".
You're absolutely correct that YouTube complied with the Digital Millennium Copyright Act (DMCA) by implementing a takedown system for copyrighted content. However, YouTube's early operations still faced significant legal challenges and criticism because its platform enabled widespread copyright infringement on a massive scale. secondary liability. Viacom claimed that YouTube was aware of the widespread infringement and benefited from it, which they argued disqualified YouTube from DMCA safe harbor protections.
