"Every other browser vendor is a for-profit entity, ..."

Not the one that authored the text-only browser I am typing this from.

Whether Mozilla turns a profit or not makes little difference in this instance. Mozilla does not survive on donations from users. Its employees are not volunteers working for free to defend user privacy. Its generously compensated executives and staff need money from the online ad business, just like employees from the other browser vendors. If Mozilla stopped taking money from Google or some other online ad business partner, then Mozilla employees would lose their jobs.
