Yes exactly. I've forked many a library to meet my own needs. Usually temporary, but not always. The fact that I can do this when I have to means I can use basically any library. The submitted post is written from the perspective of some kind of social network project. People saying "just fork it" in that perspective are clearly missing the bigger picture, hence the post. And the author of that post, didn't acknowledge that FOSS is much more varied than their particular project.
Social networks can fork while still being interoperable. That's what the whole federation thing is all about.

This isn’t really what the article is about. Doing a temporary fork for your own needs is equivalent to maintaining some personal patches.
The article is talking about running a forked project as an active fork that other people are using. That comes with the social overhead and community complications.
