WHAT IT’S REALLY ABOUT

California BASE Act targets trillion-dollar platforms’ self-preferencing to restore competition

  1. Senator Scott Wiener introduced SB 1074 (the BASE Act) to bar dominant mega-platforms from favoring their own products and services over competitors on the platforms they control.
  2. Speakers argued self-preferencing by Apple, Google, Amazon, and Meta raises prices, reduces consumer choice, degrades user experience, and suppresses innovation—especially as AI accelerates new company formation.
  3. Y Combinator CEO Garry Tan framed the bill as “anti-corruption” rather than anti–big tech, emphasizing that access-gatekeeping (app distribution, search discovery, interoperability) prevents startups from competing on merit.
  4. Founders described concrete harms: alternative app stores forced to rely on EU law, iOS interoperability limits disadvantaging third-party wearables, WhatsApp platform restrictions and punitive fees targeting AI competitors, and accessibility-oriented AI assistants blocked from basic OS capabilities.
  5. The bill sets thresholds (>$1T market cap and ≥100M monthly US users), specifies prohibited conduct (e.g., search manipulation, MFNs, use of non-public data, tying, denial of portability), and would be enforced via private actions or the California Attorney General under Cartwright Act mechanisms.

IDEAS WORTH REMEMBERING

5 ideas

The BASE Act is designed to target a narrow class of “gatekeeper” platforms.

It applies to platforms above a $1T market cap and 100M+ monthly US users, aiming to constrain only the firms with structural control over core digital infrastructure.

The bill shifts from case-by-case antitrust to explicit conduct prohibitions.

Rather than relying solely on slower, precedent-bound litigation, SB 1074 enumerates specific banned behaviors like search manipulation, MFNs, and misuse of non-public third-party data.

Speakers argue “open access” is now essential for the AI-driven startup wave.

With “vibe coding” lowering the cost to build apps, the bottleneck becomes distribution and discovery—areas controlled by incumbents through app stores, rankings, and interoperability decisions.

EU regulation is presented as proof that competition can force platform changes.

AltStore’s founder described how the EU’s Digital Markets Act enabled alternative app stores and pressured Apple to allow emulators—changes he claims wouldn’t occur absent legal compulsion.

Interoperability restrictions are framed as consumer harm, not just startup harm.

Examples included Apple limiting third-party smartwatch capabilities and messaging lock-in (green/blue bubble dynamics), reducing consumer choice by making rivals’ products functionally inferior.

WORDS WORTH SAVING

5 quotes

At the end of the day, all of these behaviors come down to one thing: massive, dominant corporations favoring their own products and services over their competitors. Uh, it's called self-preferencing.

Scott Wiener

If they want to reach users on a phone, they have to go through Apple's App Store, the worst DMV in the world. Arbitrary rules, opaque rejections, a thirty percent tax on every dollar their users spend. No appeal, no alternative, just the line.

Garry Tan

The minute that same computer fits in your pocket, the minute it becomes a phone, you lose almost all of that freedom.

Garry Tan

All this exists only because European law required Apple to allow us to exist, not because Apple wanted to, but because regulators said, "You don't get to own the platform and the playing field."

Shane Gill

No one is coming to save us. California must lead because right now it's really quite unclear who else will.
