I appreciate the fact that most analysis is biased towards US/EU focus, but the reality is that 1) the most-commonly used models are trained and distributed by US/EU-based organizations and 2) much of the foundational content (e.g., Common Crawl, Pile) was sourced from Western rightsholders.
Furthermore, I am familiar with the recent statutory movement in Japan, but isn’t Japan a member of WIPO? Isn’t it therefore bound by WIPO treaties like DMCA/WCT?
