I’m almost certain it’a troll, maybe even a previously banned one. Given their username it would be very ironic otherwise, considering that so far, in the week since they’ve created the account, they’ve only commented in order to rail against things that respect user freedom.

Eh, while I agree that some recommendations are dodgy at best, I’ll argue that Wireguard is not only adding to security, it also makes Fail2Ban obsolete. Due to the way it works, you’ll completely hide the fact that you’re even running a SSH server at all, and this includes even Wireguard itself. More importantly though, it’s pretty much impossible to set up Wireguard in an insecure way, whereas SSH provides you with plenty of footguns. You’re not risking locking yourself out either.

Also, security comes in layers.

Exactly. No root login and no password login will do just fine as basic measures, but after that Wireguard is perfect tool for this, no weird rituals required and also quite useful for any other services you don’t want and/or need to expose to the internet as well.

Yup. Even assuming this would actually work as advertised, who would actually buy this over a regular printer?

Like, how often do you run into a situation where you need something 3D-printed while on the go, but simultaneously have enough free time to set this thing up in a protected area and wait a long time for the print to finish? Not to mention that you just happen to have brought with you the proper filament as well.

Furthermore, this thing…:

• … doesn’t look like it holds regular spools.
• … looks like a repairability nightmare.
• … would surely be sold at a premium while being worse at everything except portability.
