Highly likely not, so these content creators will still not get enough advertising revenue from their videos on these other sites.
They may may be ultra liberal with regards the nature of the messages conveyed via the content hosted on their respective sites in order to build up traffic to attract advertisers but once they have attracted enough traffic and are earning enough advertising revenue, they can then dump those content creators who are a liability to their advertising revenue, just as Google, whose worldwide advertising revenue surpassed all print newspaper advertising revenue in the U.S. in 2012 and can now quite literally fart in the faces of creators of You Tube videos deemed to be too controversial in the eyes of their advertisers - who at the end of the day call the shots.
So I wouldn't be surprised if they eventually get rid of creators whom they deem to be 'deadwood' from their sites to save costs and free up more storage space and Internet connectivity capacity for the more 'productive' content creators.
One of my uncles was a journalist and so was my grandfather but looking at how media today, whether print, on the Web or digital media are struggling to survive and are grasping for increasingly scarce and elusive advertising revenue.
So I would not advise any school leaver to pursue a career in journalism, since they could be out of work in their 40s, burdened with family, children, a mortgage on their homes, a car loan to pay off and perhaps part of their student loan as well.
