Rubi does not stream or provide any video. Playback happens entirely in Safari, under your own account. The subtitles it shows come from the subtitle data each site already serves to you while you are signed in. Rubi does not store, export or share that data.
A Netflix or Disney+ subscription is required for those services. YouTube works for free.
