My point really does stand. You might gradually allow erosion of your rights until you find that none are left. It is so easy to say "I have nothing to hide" until you find that actually you do have something to hide for reasons that are not immediately obvious.
I am not saying that using Zoom will have nasty consequences but I am saying that the attitude that abrogates responsibility for your own privacy might have unintended consequences. If it becomes common place to simply say "meh" we might not like the world we get instead of the world we might wish for.
My Old Saxon friends have a rather more robust attitude to privacy concerns than you mate!
