Very unlikely. YouTube is integrated in to most modern media products e.g. TV's, bluray players, consoles etc. On these, these is pretty much no alternative. And for most end users, it works well.
And any alternative that exists, is likely to be sued out of existence by copywrite holders for using game content without permission etc. Google are just covering there arse.
It's a business, with a product you've been happily using for free for years. If it were owned by Apple, trust me, it'd be way more limited and protective. You'd probably have to wait for months for your videos to be 'approved', before being listed.
