I would be surprised if Mozilla doesn't charge everyone who is available out of the box. If they don't, they should.
I don't think there should be a default. New users should be presented a list to select their preferred search engine. This could be an educational effort; many users are likely unaware that there are alternatives. Many users don't care, because they don't understand the difference. A brief onboarding experience would help increase awareness, and it would avoid the codependency problem Mozilla itself created.
