1. was about a different flaw in your argument, not 6 above. That one is also wrong, see X levels above re video calls which you don't need to explicitly delete for them to disappear from malware's view without Recall

There are a number of things that do disappear. But when you put them in the line next to bank credentials, private pictures, passwords, and private documents, they pale in comparison.
Re: awareness. Are you saying the only MS problem is they are not marketing capabilities enough? Assuming the video calls point is addressed, your whole "feature is extremely bad" argument is that it is on by default, and one has to know to do something to turn it off if they don't want it?
