“ You can see similar features in GitHub’s smaller competition Codeberg, GitLab, BitBucket, and Gitea. These competitors don’t offer other, major code collaboration tools, and their Pull Request-like features aren’t just there to help users come from GitHub.“

That's where I stopped reading. GitLab’s Merge Requests are on par or even more robust than GitHub’s Pull Requests.

This person clearly hasn't used GitLab; otherwise, they wouldn’t say this.

Blank statements like this one undermine their core argument.
