Yeah I think this clarifies the core issue with this kind of thinking (imo).
The venn diagram between 'mechanics that make games fun' and 'dark patterns' (as described by this site) is basically a circle. The important thing isn't the patterns themselves, it's that they're used to make you spend money on microtransactions.
Looking at just the mechanics divorced of any context of the surrounding business/marketing/monetization is missing the point.
