Cory Doctorow and Joe Betts-Lacroix on Adversarial Interoperability

From Y Combinator · Published Jul 21, 2020 · Watch on YouTube

TL;DR

Adversarial interoperability (“adversarial interop”) lets startups turn incumbents’ customers into their own customers by plugging into a platform without permission, as historically done with Samba and Apple’s iWork. A thicket of legal tools (DMCA, CFAA, tortious interference) now makes this legally risky, but the hiQ Ninth Circuit decision shows scraping can be protected.

Key insights

  • Adversarial interoperability has been pivotal in tech history (Samba reverse‑engineering Microsoft’s SMB; Apple cloning Microsoft’s file formats for iWork).
  • The current legal environment (software patents, DMCA anti‑circumvention, CFAA used for ToS violations, tortious interference) creates a “kill zone” that deters compatible products.
  • A theory of change: doing something legally fraught but loved creates a constituency for normative and legal shifts, plus surplus capital to fund legal battles.
