This scenario however is "I take my personal data an run it through tools to make my life easier" (heck, even backup could fit the bill here). If I'm allowed to do that... am I allowed to do that only with tools that are perfectly secure? Can I send data to the cloud? (subcases: I own the cloud service & hardware/it's a nextcloud instance; I own it, but it's very poorly secured; Proton owns it and their terms of use promise to not disclose it; OpenAI owns it and their terms of use say they can make use of my data)
