yes, we don’t need open source if a secure service can be provided. Which Open source biz models still work? seems none

I have observed similar trends within the community. One approach is exemplified by Mitchell Hashimoto, who created Vouch, a community trust management system that relies on explicit endorsements to manage participation in open-source software projects (https://github.com/mitchellh/vouch). In contrast, Adam Jacob and his team have restricted external contributions to their OSS projects. Instead, users can submit issues with their desired feature requests, which the Swamp team or AI agents will then implement or use to fix bugs. In an era where coding has become popular and, at times, less rigorous, I fully understand that OSS maintainers, particularly those working on Open-Core business, will continue to limit external contributions more and more.
