The magnetic plate indeed warps, not due to heat though but the material on it warping. I saw that on both the i3 Mega as well as a Prusa MK4S with PETG and ABS. Printing big solid objects close to a corner would cause the corner to be lifted up, as the warping of the object is often times stronger than the magnetic plates. Probably gives you an idea of how much force a glass plate has to withstand, especially with badly warping materials like ABS. You can counter this issue with some strong clamps. Doesn’t happen on most prints anyway, only on really large and solid ones. The magnetic adhesion in the center is strong enough for anything.
That’s guilt by association. Their viewpoint is awful.
I also wished there was no security at the gate of concerts, but I happily accept it if that means actual security (if done reasonably of course). And quite frankly, cute anime girl doing some math is so, so much better than those god damn freaking captchas. Or the service literally dying due to AI DDoS.
Edit: Forgot to mention, proof of work wasn’t invented by or for crypto currency or blockchain. The concept exists since the 90’s (as an idea for Email Spam prevention), making their argument completely nonsensical.
