Yea about the filters someone explained that wery well, since its open source you can have diferent aplikacions that will be used to watch videos on lbry. For example we could have lbry kids app that will allow only content for kids. But if we adults want to be able to see all we can use app that doesnt block anything. So its on us to have filter as ve like not on youtube to tell us what we are allowed to see. Because on youtube many people are banned just for spreading the truth. Thats why lbry is created at first place…
