You’re completely ignoring the context. This is essentially about checkboxes. “Enabled by default” would mean tracking is always on, but doesn’t tell you if it can be disabled by the user. In the realm of privacy choices in software, we then started referring to these as “opt-in” (default off) or “opt-out” (default on) to communicate the default setting + the ability to change it. Advertising trackers, for example, are mandated by law to be “opt-in” (they pre-select the checkbox for you of course, without submitting, but that’s a whole other story).
