I suspect there's a sideline wink and handshake agreement to feature associated companies and indirectly promote them as case studies, etc. as the maintainer maintains. Not that that changes anything this is still a great arrangement and hopefully a positive example for our industry, but Smallstep and Tailscale are both trying to gain an authoritative hold in the production identity space and a little name dropping here and there by <famous dev> certainly doesn't hurt (:
