Using WhoisGuard for their domain is so not a problem. Namecheap gives you that for free and by default, and it cuts down on spam mail from other registrars.

Bitwarden is open source and self-hosted. This is a better trust model than any of the other offerings by a mile.

I have no criticism of the service or WhoisGuard, just the idea of that kind of site using it.
