I don't use anything from Microsoft, Facebook, Instagram or Apple. No Amazon, Netflix, Paypal or eBay accounts. I do have an Android phone, alas, but I'm not really dependent on Google for anything. I have a few offline games and other than that, it's just texting and calls. My next phone will be an open-source one.
As for email and calendar, I am de-Googled. Basically, all the big American tech firms could disappear tomorrow and my personal computing environment wouldn't notice. (There'd be worldwide chaos, of course... but my little corner of the Internet would be just fine.)
