Okay, since you need a definition for everyhting... try saying something against Elon (e.g. like I recently did in a comment on YT) and you'll have people coming in and justifying what he says and does, like it was good and well and not detrimental to society and the world; the same applies to "billionaires and trillion dollar companies" and that's what OP meant with defending them. If it wasn't obvious enough.
