This is concerning, certainly, but the failure mode is a liveness failure for new participants which isn’t the worst situation, especially since you can change your bootnodes via configuration.
It would be great to see more boot nodes that are hosted independently (e.g., in someone’s basement), or at least spread across many different datacenters in many different jurisdictions. This doesn’t mean just different AWS regions, because all of AWS (except China, sort of) are under the jurisdiction of the US. Ideally we would find some smaller locally owned/operated DCs in various jurisdictions including places that have a bit of a history with censorship resistance and privacy like Iceland, Sweden, Switzerland, as well as some jurisdictions that are just non-functional like many “developing nations”.
