Because Marxism is a very particular political ideology with very sharp limits: "anything that advocates for prohibition of private ownership of means of production is a Marxism". It doesn't need to be quoted. Capitalism on the other hand, is all of the world economy and it has no alternatives, at least those are not being tried anywhere. People complaining on "capitalism" are simply complaining that "world is unfair". I can't take any of those complaints seriously. One thing is to complain on particular issues in particular countries such as - overly high taxes, or overly low taxes on rich, corruption, zoning, etc. - but complaining on "capitalism" is like saying "i don't like this world, give me another one".
