Lots of things are hard. It's not AWS's problem that your job is hard. If you can't do the hard work to run your business, your business doesn't get to run.
If AWS cancel any customer that fails to succeed to an entirely arbitrary standard at problems that are "hard" then yeah, it kinda is AWS' problem. Or more specifically it's now Silicon Valley's problem because when these firms make identical decisions within 24 hours of each other nobody in politics is going to treat them all as unique and special snowflakes. The left have seen that they can apply pressure to get anything that isn't controlled by leftists erased from the internet, so they're going to amp up the volume 10,000% now. And the right have been complaining for years that tech firms have been captured by the censoring left - how will anyone ever convince them otherwise now? Claiming that Parler was full of Nazis? It's a tired strategy, it doesn't work anymore, the left describe anyone who isn't the left as Nazis and fascists. It won't convince anyone.
That's obviously not the case. It's very clearly Parler's problem. I don't see why AWS should accommodate a customer just because the customer's problems are "hard".
The rest of your post is basically irrelevant imo, I'm not going to respond to rhetoric about party.
