If one of my future ancestors gets away with murder because i didn't give some company my DNA, then good for them!
One of my relatives did the whole DNA thing. Fortunately, I don't have a past where that's going to matter and, at the end of the day, it probably won't matter much for me. I served and so they surely still have blood samples. I had security clearance so they may well have already decided to use said samples to learn my DNA.
Man, my future serial killer heirs are going to get caught quickly. They're going straight to prison.
As an aside, I'm one of the rare people who can do quite a bit of traveling without ending up on a CCTV. I don't have anything important to do with that information, but it's something I can do. I've even paid attention to the various survielence cameras that could track my vehicle while it's on the road. I can go quite a ways into the nearest areas without being spotted on any of them - that I know of...
Of course, while I do leave home without it, there's always my cell phone to track. Though, if you go about 15 minutes north of where I live there's no cell service and service won't return for about 30 minutes worth of driving - longer if you get off the main road.
I'm not like a crazy prepper or anything. I just pay attention to that stuff. They've already got enough matching DNA (and probably my own DNA), so I'm not getting away with anything serious. It does mean that I can drive in a spirited manner without fear of being caught. So, there's that.
Anyhow, to be on-topic...
There's a complete archive of Etcher versions on YouTube. They all more or less do the same thing. If you don't like the version you've got, just grab a different version. If you want to protect yourself against future versions, hold onto that version. It should continue to be fit for purpose well into the future.
Also,it appears that they removed telemetry. A part of me wishes we had more telemetry with Linux, just so we can settle the issue of which distros are more popular!
