I think your point is valid for an equivalent understanding of unrestricted (or popular) access. All YouTube kid videos lead to toy review/recommendation videos eventually. However, the internet is a big place, and if I have something in mind that explores an idea I can usually find it somewhere online. In contrast, legacy media like PBS doesn't generally allow for picking relevant content— the unrestricted or passive mode is the only mode available without scheduling your day around TV (something I'm not keen to encourage). So no, not equivalent, but not necessarily worse.
