It's natural for people to use the word "capitalism" to mean "how capitalism appears to an average person in the world today". I think many people who complain about "capitalism" would acknowledge that there are things that are "technically" capitalism that are okay and even exist, it's just that they think what capitalism is by and large is the form of bad capitalism you mention. Just like nowadays what someone means by "a phone" is different from what people meant by that 20 or 50 or 100 years ago.
