I am an IC, but other than that all of this was true for me during the 3 years I mainly worked remote. I definitely can echo what you said about people being dickish and bludgeoning people on remote calls - especially when we didn't enforce a camera policy. People said things that to that point in my career would have been absolutely shocking, and I never have heard anything remotely close in an office setting. I guess it's probably easier to be that way when working with people who are nothing but a name and a title to you, but I don't know.
