Exactly, who really knows what data has unwillingly been extracted. Sure some people may not care ~ until one day. Oops! maybe a security update would have been usefull.
Like @unaegeli I use few apps etc. but even on my PC I use thunderbird not a web email app, and even then my data is encrypted on an SD card, not the main memory.
My thinking is that I have other peoples personal data too, emails addresses, and I’m sure they would like me to do my best to keep it secure.
