If you mean the fact that we have true randomness, just read about how secure random number generators work, like urandom. It’s not some industry secret, they’re in every computer and likely every smartphone out there, and have been around for twenty years at least.
If we’re talking about the same thing, then afaik their whole claim is that we aren’t in a simulation, because we have true randomness which can’t be created in software. But it’s not necessary to create true randomness in software to have it in said software.
Although I haven’t read the full paper, and am going off what people wrote about it in comments.
For what claim?

That having true randomness in machines means the study is debunked?
