Either way, this is an indictment of Ubiquiti
Even if all of these allegations are true, I'm not sure if this makes Ubiquiti come out looking better or worse. If one person can cause this much infrastructure-level damage, what does it say about their infrastructure security architecture and overall commitment to security?
One of the reasons I've been sharply critical about the mass-centralization of vital data is that it increases the value of a security breach to obscene levels. Even if an inside threat isn't inherently malicious, what about blackmail, extortion, etc.? There are many parts of the world where grabbing somebody's family and cutting off parts until compliance is reached is not exactly out of the question. I would never blame that person for complying. And if the value of a large-scale breach of, say, Google or Microsoft's cloud-hosted workspaces is in the hundreds of millions or even billions of dollars / Euros / pounds, how do you even defend against some group with the budget and discipline to make a serious, no-holds-barred attempt at that? With the current state of international relations, can we even rule out governments (including the "civilized Western" ones) if they're not in it for profit, just creating mass damage?
Our industry has had many bad experiences caused by the technological equivelants of biological monoculture, and instead of learning from these it seems to be betting harder and harder on this.
Even before information technology, there was an adage about putting all of your eggs in one basket.
