I think you’re missing the point here. You’re claiming Google only pays Mozilla to have a competitor, yet they also pay apple even more money for the same thing in an area they’re just competing.

The point is that there is competition in the default browser search space, it’s just that Google pays more than anyone else.

If Google stopped paying Mozilla tomorrow, someone else would pay them for the same default search engine spot. It might not be as much, but it would still be a significant amount.

A few years ago it was Yahoo that footed the bill.
