I didn’t say I’d be pissed if my contributions are turned away. Every project sure is entitled to say - we don’t need your contributions. But that’s not what happened here. They received this blog author’s contributions, suggested revisions - which they seem to have made and spent time on, and then to only flush them out at the end.

By your logic, if you don’t want someone contributing to your project, just ignore the contribution or say that you don’t want them - do not take it without due credit.

You can, of course, fork the project, or do whatever you want with the code.
