Is the awful taste of canned chickpeas the can or the chickpea?

I like chickpeas in things (e.g., hummus) but any time I try to cook with them they’re overwhelmed by this awful flavor. Do you know the nastiness I’m talking about? Is that due to something in the canning process, or is it actually part of the chickpea flavor? I don’t get it from other canned legumes.

If it’s from the canning process, is there a way to get rid of it? I’ve tried rinsing them but it didn’t have much effect.
