Unfortunately, this seems like a waste of money given how similar cases have panned out.

I don't buy it. Using aws in the first place is suspicious. The site was always suspicious. It rose to prominence effortlessly. Required a ton of identifying information to make an account.

They could host it on their own server or a patriot friendly host they just won't, because it has served its purpose.
