The way how they can just block search results for certain youtube channels is a blindingly obvious reason why youtube should have been partitioned away from them long time ago.

You will find youtube videos that mention these people (Tim Pool, Liberal Hivemind, Anthony Brian Logan), you will find their facebooks and twitters but you won't see their actual channels.

And the fact how they cross-use data from searches and data from watching videos back and forth is an even bigger reason these companies should be split up.
