In tightly controlled ecosystems the default state is effectively what most consumers will keep and use.  This is sometimes informally called the power of default.  Entire billion dollar markets can rise and fall based on something  as simple as an opt-out versus opt-in policy.  It&#x27;s a little like that Supreme Court ruling that said &#x27;&#x27;the power to tax is the power to destroy&#x27;&#x27;.  The power of default is not much different especially when you control the entire underlying OS.  Anti-trust regulators are right to focus on what these default settings are.
