Good work indeed. The key is to not use any of the Big Tech services. And there are alternatives if you make the effort; unfortunately the young generation for the most part don't. The real bugger, though, is the mobile phone: it's Google or Apple period (Purism never took off!). I'm not young anymore but I still have to work. And these days I simply cannot function without my smartphone; they've introduced authentication checks which push a message to my phone(response required!) for every system I interact with. That's minimum 8 to 12 times a workday. Just think how this process could be abused in the beautiful future!?
