The bottom line is that the platform is often stronger than the personality[1]. There are TV personalities/pundits etc who are fired from whatever network they were on for some misconduct, and even though they were a very popular draw on that network (i.e. platform), they often can't recreate that success elsewhere because they were dependent on ingrained user habits. Yes users care about differentiated content sometimes, but oftentimes the lowest friction thing wins out if it's "good enough". If my user behavior habit is "go to youtube and check out what new videos are available from my subs", I'd only visit a non-youtube site if I'm really into that non-youtube content. Otherwise whatever comes up in the queue in a low friction manner is "good enough". Some exceptions exist of course. Conan O'Brien would be a good example.
