Confidence: Verified (primary IndieWeb wiki).

For Candid client work: The discipline that makes social-media-dependent SMBs durable. Publish authoritative content on the business's own (owned) domain first; syndicate excerpts/teasers to LinkedIn, Instagram, etc. with a canonical link back. When a social network shifts algorithm or shuts down (or, more commonly, when an ad account is locked), the source-of-truth survives. This is the operational counterpart to Doctorow's prescription: "right of exit" requires interoperability, not just open source for content channels specifically.
