You are both right. Everyone needs a microphone (actually in some arrangements you can use one between two or three, depending on how reverberant the room is), but only one microphone should be open ('on') at a time.
To set up this type of hybrid session needs
careful design, especially where the ideal equipment is not
available. But it can often be done. For example, in some room
layouts, one or two 'roving' microphones are practicable, in
other layouts not.
