Opt-Out Was the Whole Problem
The single design decision that doomed Muse Image was consent by default. Meta did not ask public adult Instagram users whether their photos could seed AI-generated images - it enrolled them automatically, then buried the escape hatch inside a multi-step settings path under Sharing and Reuse [1]. Private accounts and users under 18 were spared, but everyone else was in unless they hunted down the toggle. The mechanism inverted the usual burden: instead of Meta earning permission, users had to discover a feature they never asked for and revoke it manually.
That inversion is exactly what the loudest critics attacked. SAG-AFTRA argued that anything short of a clear, conspicuous opt-in was unacceptable for using people's images this way [2], and CAA framed it as a consent violation on principle - no third party, human or model, should reuse a likeness without documented permission [2]. The technical detail that turned unease into alarm was that anyone could invoke a person's likeness simply by @-mentioning their public handle, converting a follower count into a deepfake surface. Reporting also noted that Meta did not notify people when their likeness was used [1], so the person being generated had no signal the tool had touched them at all. Opt-out was not a minor UX misstep here - it was the entire failure, because it treated participation in AI image generation as the default state of having a public profile.
