## Summary
Mozilla's policy team has published a new advocacy post arguing that momentum for US digital competition reform has reached an inflection point, with bipartisan backing for three Senate Judiciary Committee bills: the American Innovation and Choice Online Act (AICOA), the Open App Markets Act (OAMA), and the America Act. The organization frames current antitrust efforts as distinct from prior failed attempts, citing broader coalition support spanning startups, mid-size tech firms, civil society groups, and cross-ideological think tanks.

The post emphasizes that dominant platforms' integration of AI services into existing ecosystems is deepening structural barriers to competition, making legislative intervention more urgent. Mozilla specifically highlights user choice, interoperability, and the ability of independent privacy- and security-focused products to compete on merit as core concerns. The advocacy follows Mozilla's long-standing support for AICOA and its participation in a recent Senate briefing co-hosted by the Bull Moose Project and Public Knowledge.

## The three bills and Mozilla's policy framing
- **AICOA (American Innovation and Choice Online Act):** Would prohibit dominant platforms from self-preferencing their own products and services over competitors, addressing search, marketplace, and ecosystem integration practices.
- **OAMA (Open App Markets Act):** Targets mobile application distribution by requiring platforms to allow alternative app stores and sideloading, with implications for iOS and Android gatekeeping.
- **America Act:** A broader competition measure also before the Senate Judiciary Committee, though specific provisions were not detailed in the source.
- **AI integration concern:** Mozilla identifies the embedding of new AI services into existing dominant platforms as a mechanism that perpetuates and accelerates market power, creating fresh barriers to independent challengers.
- **Structural vs. behavioral framing:** Mozilla distinguishes between punishing success and ensuring that structural barriers do not prevent independent innovators from reaching users who want alternatives.

## Why it matters
For the open-source browser and privacy-software ecosystem, passage of these bills could reduce platform-level discrimination against Firefox and independent alternatives on iOS, Android, and search defaults. The legislation also intersects with ongoing EU regulatory pressure under the Digital Markets Act, potentially creating transatlantic alignment on interoperability mandates that benefit Linux and open-source mobile projects.
