I've long since started assuming I'm getting data-raped by tech companies until solidly proven otherwise. I am rarely proven otherwise, let alone solidly.
Also, don't fall into the cloud services trap - coyly called SaaS or PWA: those "apps" don't run on your machine. Your machine is just a fancy terminal. The trap is, even if your machine runs free software, it's still a terminal and you're still getting data-raped.
That's why cloud applications need to be fought every step of the way. As long as the application runs locally and it's not closed-source code made by greedy big data for-profits, there's a way to escape the corporate surveillance. If any one of those two premises is missing, your privacy will be invaded with 100% certainty.
