why don't you use them all? if it's free storage, who cares?
If you're doing it for the money and want that juicy ad revenue yt gibs, then play by the rules... but also, you could always offer the same plus "problematic" videos on other platforms, or build your own, like Corridor Digital.
if I were to start a youtube channel today, I'd also automatically upload my videos to every platform under the sun if it offers free storage, just in case. It's free after all, exploit it like a based nigger. YOLO.
