I see your point, in fact I am against the term Neo-colonialism for this exact reason. Neo-colonialism is bad, but next to the horrors of actual colonialism, it is a walk in the park. And naming economic policies which artificially increases the dependency of a foreign country in your economy, after a policy of mass extraction, neglect, violence, and even genocide really removes the horrors from the latter.
However it has been over 500 years since feudalism. People today are still very much living with the consequences of colonialism, some people are in fact still living under colonial rule (notably in Western Sahara and Palestine). The consequences of feudalism have long passed. I think it is fine actually to conflate the horrors of capitalism with the horrors of feudalism. 500 years ought to be long enough.
