Wow. I'm the creator of Calva and I can tell you that I do not have an opinion on how to use it. I would never say something like that, and now I wonder what I could have said that was interpreted this way...
By default Calva Paredit overrides three or so keyboard shortcuts. This is to help the users to not accidentally delete brackets, which in turn keeps the support questions down about broken Clojure code. I have tried to make it super easy to disable these overrides. There's a command for it. There's a button in the toolbar for it, and there's a setting for it.
There's also a setting for removing all Paredit bindings, even those that are not overriding any default ones. (This setting is for people who use Paredit, but want to provide their own shortcuts entirely.)
