Popper's standards exclude sociology, psychology, theology, economics, and most of the "soft" sciences. This annoyed many people who claim to be doing science. Kuhn was willing to consider them science, but had to redefine science to make that work.
Falsifiable theories allow reliable predictions. So they lead to engineering, and stuff that works. Although Popper's position is currently unpopular, he wasn't wrong.
Richard Feynman called "soft science" a pseudoscience, which I completely agree with.

Humanities departments around the country essentially appropriated the good name of science at add more legitimacy to their "soft science". It's similar to how "christian science" or "scientology" appropriated the good name of science to legitimatize themselves in the eyes of the public. Creationists have even created creationism "science" to make themselves look more legitimate.
