For instance, the Roku interface to YouTube does not allow channel blocking at all, and down votes don't stop videos appearing. So the claim they allow that control is not fully true.
And don't get me started on their hate-filled recommendations.

'Companies have strong incentives to resist studies that could suggest they are responsible for harms involving their products. That’s why future studies will depend on innovations in adversarial data access, ethics and privacy. Researchers should prioritize methods that don’t rely on companies, while supporting laws to require algorithm makers to collaborate with researchers.' https://www.nature.com/articles/d41586-023-01521-z
