Don't try to work around it. If you found in your user studies that people wanted to use right click, you'll be inconveniencing the majority if you remove that behavior. Speaking for myself, I get mildly frustrated when a web app doesn't give me a custom right click menu, because discovering whatever they chose instead is much harder.

If you could find out more about why people like OP dislike overriding the default behavior, you might be able to provide those functions that they are missing. If it's devtools, you're out of luck, but someone who needs those probably already knows ways around the click hijacking.
