The whole blog post is also taking a stance. What is criticized is the specific stance taken by Codeberg. TFA seems to state that Codeberg should allow projects of all kinds to be hosted on their service (though apparently artificially limiting their resources would be alright).
One of them is a website that hosts source code from other users, their "stance" is arguably more important because of that. The other one is just a personal blog, completely different subjects. I created an account just to reply to this.
