As a frontend developer I don’t like Tailwind for several reasons, it brings the styling into the structure. As a frontend developer Tailwind is at a forefront of what I would consider bad practice and encourages a code style which would be a nightmare for me to maintain.
That said. Tailwind seems to be loved be people who are not professional frontend developers. It seems to be just the right tool for people who are not necessarily proficient in CSS. And perhaps people like me (and the dead sibling) need to learn to let go and allow other people to have the tools which makes it easier for them to do the job which they are not experts at. For that reason I understand Tailwind, even though I don’t agree with it.
