I would love it if there was a smaller company like Framework or System76 that made printers that weren’t enshittified. Something with open firmware and hardware that also could be easily repaired. Or at the very least an open standard that existed for printers to use. I know companies like HP or Epson wouldn’t buy in, but maybe some smaller players could join in with that if there was.
My understanding is that it’s just not as secure. Any open port can be considered a potential way for a hacker to get in. Of course, that doesn’t mean it will 100% happen and you will get hacked, but at least in the case of Tailscale, it does it in a secure way that makes it so you don’t have those open ports. Basically, it’s not bad to just expose them to the internet, it’s just not as secure as using tools like Tailscale.
For something with fitness tracking, I’ve been using the Garmin Forerunner series for years. Recently though, I’ve been using the Pine64 PineTime as my main smartwatch. It doesn’t have much for fitness tracking, but if you’re looking for a basic smartwatch it’s pretty nice!
