You are right, but people who want their files and usage data 100% private and protected should be able to make that choice, especially these days. If a software company needs to access my hard drive in order for me to keep using their software, then I'm not going to use their software. It's that simple.
This is another whole can of worms, I've been using/developing software for over 35 years and I have accepted reluctantly that I have no control over privacy while using the current operating systems.
Don't get me wrong, parts of me wants to be that fighting spirit that once used DOS 2/C64/ATARI800XL who had TOTAL and I do mean TOTAL control over their machines! But this is not how it works anymore.
