Ohhh, this is so bad. (“We take up to 30% plus we keep a copyright to your work that we already made money off of, forever”?) And you know that Facebook is big enough, and in some countries, ubiquitous enough, that if they launch this, even with these terrible terms, people will use it. Lots and lots of people.
The thing is, Facebook effectively is the internet in many countries. So maybe that’s true in the US (especially given Patreon, etc.), but outside the US? India, Brazil, Indonesia, etc.? If it’s the difference between “I get something (even if thoroughly plundered by FB) and I get nothing”? I don’t know.
