Where's the cutoff? Lay your own fiber to your own datacenters? At some point economy dictates that you rent. And with Parler, I'd assume that that point comes sooner than later. I mean I don't know their funding situation, but I find it reasonable to assume that if they'd built a NOC first they wouldn't have gotten off the ground at all.
If their goal is to be a free-speech-above-all platform that is definitely going to piss off both infrastructure providers and the world of people who might attack them, then they better have the technical capabilities to back that up or they're going to get torn to shreds. Nobody else is required to help them in their misguided (in my opinion) endeavor.
And yes, it's possible that such a grand plan takes more resources than they actually have. Not anyone else's problem.
I'd love to know the risk-scenarios they considered. Could they imagine getting booted off AWS?
Something to consider on the tech front would be Starlink. What happens when the orbital layer is independent of terrestrial backhaul under ideal routing conditions? Consider the implications of a datacenter that is in space or located at a geographic location that is incredibly difficult to access. Just a decent desktop PC hooked up to a 100mbps pipe can serve a lot of traffic if the application is built properly (i.e. text-only).
For instance, the load balancing and DDOS protection products sold by Cloudflare are not the effects of some ancient mystical artifact that we could never hope to emulate. These are simple network engineering practices that can be replicated by any experienced IT staff. Sure, you might not be able to mitigate a theoretical 100+ terabit DDOS attack, but is this actually a problem in practice for your business? Even if you have ridiculous capacity, at a certain point you would still have to defer to ISPs, law enforcement and other external measures in order to restore sane operations.
Certainly, there is no perfect solution. But, the more of your stack you have under your exclusive physical control the better.
