Think of it as the Mac appstore VS the Windows App store. Mac apps (flatpak) are the same as desktop apps, but sandboxed, the store isn’t intrusive, and people found it convenient, so it was fine. Then the windows app store (snaps) launched and it did basically the same thing but slightly worse, except Microsoft (canonical) forced it down its users throats, so people hated it.

Both camps are right, from a technical perspective, snaps are fine, but philosophically, it sucks, and the Linux community cares way more about the latter than the former, otherwise they’d all be running windows.

The key insight is that the force a plane uses to move is independent of the ground, because planes push on the air, not the ground.

Imagine you put a ball on a treadmill and turn it on, what happens? The ball starts to spin and move with the treadmill. Now take your hand and push the ball backwards against the motion of the treadmill, and the ball easily moves in that direction. The force your hand put on the ball is exactly what planes do, since they push on something other than the ground (the treadmill) they have no problem moving, no matter how fast the treadmill is moving.

Plane on a treadmill is really interesting because if you understand how planes work its so obvious what will happen you don’t need to test it. Planes move on the ground by running their engines, which push against the air, the wheels provide zero motive force. It’s also why planes need tugs to move away from the gate, you can’t run the engines in reverse. Planes are not cars, but people tend to assume the thing they don’t understand works like the thing they do understand, and refuse to believe their hasty assumption is wrong even when told directly their hasty assumption is wrong.

It has the same root as the also made up word Cybernetics, hope this helps!
