What about the ban of any gun related videos? Isn't that political censorship? Did you already watch Youtube CEO's (Susan Wojcicki) comments on anything political?
Youtube is a private entity and they don't have any obligation to be neutral. They only have to pretend to be.
Everything I've read has stated the bans and deletions will go in affect at the end of this month. Down to the wire but if true there will be a lot of "where is your god now?" examples to this idea that YouTube won't enforce its own rules: https://support.google.com/youtube/answer/7667605?hl=en
Those rules don't ban everything gun related though, just selling and modification. Although if Forgotten Weapons gets caught up in that because they're for auction that would be a real shame.
There's nothing new here though. "Guns" are a special category of product that were already excluded from many online sites, e.g. eBay, Amazon, Craigslist, and more. That's why you have GunBrokers, Bud's Gun Shop, Armslist, etc.; there's a whole parallel ecosystem of sites related to guns that exist because the biggest sites in those fields don't allow guns. Having a separate video site would fit well into that paradigm.
