Platform Lock-in
What it is
Designing ecosystems that make leaving prohibitively costly through data formats, social networks, learned skills, and accumulated content that cannot be transferred.
How it works
Real-world examples
- •Apple's ecosystem of devices, software, and services that work together but lock users out of alternatives.
- •Social media platforms where years of connections and content cannot be easily moved to competitors.
- •Enterprise software with proprietary data formats that make migration to alternatives extremely expensive.
Ethical guidelines
- ●Users should own their data and be able to export it in standard formats.
- ●Interoperability standards serve users; proprietary lock-in serves only the platform.
- ●Competition requires that users can switch without losing their digital lives.
How to defend against it
- ►Regularly export your data from platforms as backup.
- ►Prefer platforms and tools that support open standards and data portability.
- ►Consider switching costs before deeply investing in any single platform ecosystem.
From the Defense Playbook
Pay for free trials and subscriptions with a virtual or single-merchant card number that you can cap, pause, or close yourself, so that a renewal you did not want fails at the payment stage instead of depending on the merchant's cancellation process.
Before entering payment details, spend one minute finding out how you would leave: search the service's name with "cancel", read the cancellation terms, and treat a hard or hidden exit as a price you are being asked to pay.
Every playbook entry states how strong its evidence is and when not to use it. Browse the full playbook.
