I think money spent on VPN and mdn+ goes more directly to funding Mozilla. But I would actually prefer to see a Mozilla that tries to become fiscally independent of partnerships like Google and fully commit to the donation model (+ maybe selling a few products like VPN and mdn+) closer to what Wikipedia is doing.

Funding Mozilla is still a step removed from "used to develop Firefox". Mozilla has ridiculous overhead, including a 5 mil per year CEO salary.
