Google has an inordinate amount of money to spend on inordinate amount of content review. Deleting history and evidence of war crimes is Evil; good thing Google had abandoned their earlier aspirations.
If youtube can't handle the load, then they shouldn't claim that they can. At the absolute lest, they need a usable appeals process. If they can't do that, then they need to own up to it, and stop allowing anyone to upload anything.
YouTube is a company that is beholden to advertisers. YouTube wants/pays for videos that they can put ads in front of. If your content is not the type of content YouTube can wrap in ads, and you need longevity for your videos, YouTube is not the platform for you. YouTube never claimed to be an everlasting video storage space for all your video needs, so I'm not sure why you're expecting that of them.
Video has become politicised because it is a popular medium for political topics and one which can be rapidly produced and consumed. Advertisers are perhaps influencing Google's decisions on this, but they are equally political. The debacle with the diversity memo is one example of biases inside of the company. There have been many more examples over the last years, one such example is censorship across the board of conservative commentators.
It goes on in Facebook, Twitter and so on. So we have to wait for competitors to turn up, how many years will that take? Is that a responsible route considering the foothold these companies have?
ALSO: I don't know about you, but this so-called "censoring" of conservative commentators doesn't seem to have worked. I see more young people skewing right/centre than I did 10 years ago. You can call it censorship if you want (because sure, that's probably the best term), but implying that a company selectively hosting content is the same thing as limiting the free exercise of speech is absurd.
Probably for this reason: http://slatestarcodex.com/2014/04/22/right-is-the-new-left/
