Just to clarify, I've open sourced a ton of PhotoStructure (exiftool-vendored, batch-cluster, fs-metadata, @photostructure/sqlite, sqlite-vec, and 10 more repos), but PhotoStructure's frontend and backend integrations are not open source. If PhotoStructure, Inc. ever closes, though, I will open source the repos powering the consumer product.
I've written open source for several decades, and certainly enjoyed the spoils of open source, but I've also seen a ton of bad behavior. Keeping it closed source certainly is not a guarantee that I avoid intellectual property theft or license violations, but at least I'm not just one agent prompt away from someone rebranding and reselling what I've worked full-time on for more than a decade.
