Red Hat provides support for their packages. If you're not paying for support, you don't get access to the repos. That makes sense to me. What does Microsoft gain by creating a walled garden? They don't provide support. All that they provide is hosting. The Eclipse Foundation provides hosting for free for OpenVSX, which is an amazing service to the community of people using VSCode forks that aren't allowed to access the VSCode Marketplace. Microsoft should either relax the ToS on the Marketplace or acknowledge OpenVSX as the one and only marketplace for extensions.
