This article ignores the fact that people actually used it and actually realized the benefits cited. Traditional way of using CSS I feel is still advantageous for websites (instead of apps) with a limited set of highly reused styles. Nowadays however there’s a general lack of restraint and self-control when it comes to web design, you must have a million variations of everything. In that case utility-first CSS clearly wins because there’s almost no reuse except at the per-property level.
