From what I understand a lot of Hollywood contracts (for writers, actors, etc.) include residuals for tickets sold or views on streaming services. However, streaming services did not have to provide the actual numbers of streams so people couldn’t determine how much money in residuals they were owed.

I believe there were also some questions about streamers fudging numbers to say shows were more/less watched than they actually were so it’s a big step to knowing what’s actually going on.
