All of your advice is sound enough, but the point of this video was more to demonstrate that Cloudflare (and absolutely other companies) are specifically avoiding “layoff” language in favor of firings based on “performance” to avoid paying these people even the paltry amount in unemployment they would receive. It’s not just that they’re being laid off.
I think they mean that sandboxing Windows in a VM is akin to how GrapheneOS can sandbox Google apps, not that they would use Graphene on a PC.
Happy to be corrected though!
