I disagree 100% with that. I much prefer using Tailwind for complex apps with reusable components. Because then you don't have a lot of repetition, redundancy is as much as BEM.

For static webpages (unless it is assembled by a static blog engine or something), I don't particularly enjoy it, because of the repetition.

With components+Tailwind you have as much duplication as you'd have with pure BEM.

All personal experience and opinion, of course.
