Is default browser outcome product of competition?

The default browser outcome is argued to reflect the product of competition. Professor Murphy indicated that the challenged browser default arrangements demonstrate competition's outcome, suggesting that these defaults create value that meets market tests across various circumstances[2][1].

However, the exclusivity of Google’s contracts granting it default status raises concerns. While defaults may enhance consumer convenience, they also solidify Google's dominance, as most users stick with default settings, impacting both Google's revenues and competition in search[3][4].
