Well if it's strangely hostile I'm sorry but "I need to focus on writing so I spent a few days stripping down a Linux distro" seems pretty disconnected.

I mean it's a fun project!

But it really reminds me of something I would do that isn't entirely positive.

Disconnected from what?

The reason it feels hostile is because you led with a joke about the whole thing being a big mistake, but also that the author wrote about a thing they built to solve a problem they had and ended their post by saying that it worked, and you've popped up to pitch that it might not work.
