I really wonder what sort of information sources people are exposing themselves to for "slavery still exists, and tech platforms are used to facilitate it" to be a revelation. I just don't understand the news-browsing/discovery experience of educated, tech-savvy people who somehow don't even stumble upon global news websites with tons of articles about all the bad shit that happens worldwide, and that it's not isolated incidents but PREVALENT and normal in some places.
