Can confirm this. I experienced this on my Pi3 recently with a VPN. I mean, it wasn’t the end of the world. Just that the specific docker container I wanted to use wasn’t compatible because of ARM so I had to go with a different one.

It could be bad for specific things that are more obscure. But I use my Pi for PiHole adblocking and VPN and that’s it. My other stuff lives on another machine and the Pi is set up for redundancy and it’s more reliable if power outages happen since power in means power on by default.

If you can get one for cheap and just want it for the same reason, could be alright.
