Presumably this vendor would not have all of their users using all Tor
all the time with no other browser option.

No, this would not work. We cannot make use of tons of junk relays in
the current Tor network. See my other reply.

What would work is an optional mode where the users only use the Private
Browser when they need it. For example, if 5% of these 2.8 billion users
decides to use the browser on a given day, that is something we can
handle, if they helped pay for or add the network capacity for these
users somehow. :)

We could also handle controlled rollouts to fractions of their userbase
to test the waters, and slowly add high capacity nodes to the network to
support these new users, to ensure we have the people ready to accept
payment for running the servers, and maintain diversity.
