Yes, moderators routinely downweight tutorial articles for that reason. It took us years to realize it, but tutorials aren't a good fit for Hacker News.
HN is for articles that gratify intellectual curiosity. Most tutorials don't do that; it doesn't fit with being a recipe for a task. If a recipe were to dive deeply into how and why its steps work, how they got that way, and compared other recipes that have (or don't have) similar steps, it would gratify intellectual curiosity better. But then it would be a worse recipe. It would also be more work to write.
The worst kind of tutorial from an HN point of view is the kind filled with arbitrary details that apply only to a particular program or product, like "Now put a file named foo in a directory called baz". But that is almost all of them.
