That's an interesting scenario. Let's say Google is banned from buying search engine defaults. Then Mozilla would no longer be able to sell the Firefox default to Google.

Sure, they could sell it to someone else, but without the biggest player bidding up the price, it'd probably sell for a fraction of what it does today -- which could be devastating to Mozilla, given that almost all of their funding comes from the search deal. What would that do to competition in the browser space?

Competition in the browser space is over and Chromium won. If this had been regulated earlier by preventing Google from preinstalling Chrome on all Android devices, we wouldn't be in this situation where Firefox is on life support, but here we are.

Using Firefox as a reason not to break up some of Google's hold on search seems extremely short-sighted. Besides, Edge using Chrome changed the whole browser market dynamic as more and more people are using it. Once Microsoft reaches a somewhat decent percentage of install we will be back at a two (three?) player situation.
