Those both require subscriptions for access though instead of offering an ad based tier so that already excludes a majority of viewers from being able to move over from yt and those producers are unlikely to abandon their current audiences for a possibly bigger audience under a different corporation. I think that's going to be necessary for a majority of viewers and producers to switch to another A/V distribution platform. If Netflix or MTV had an ad-only based tier and released apps for phones, Roku, browser, etc and allowed producer uploads then I suspect they could take a big chunk of Google's yt viewership and profits.
