By these examples I’d say operators hate THIEVES.

It wasn't a pinball insurrection, it was a pinball party!

Not trying to sound sexist but I've heard "don't move the machine like that" mostly from women. My wife doesn't like it because she has a smaller body mass and frame than me and simply can't move the machine as easily as I can. I believe it's a valid request when casually playing with people who can't physically move the game to disallow such behavior, but I've never seen a "no nudging/sliding" rule in organized competition.

I have also observed that people who don't own games or play them very often tend to think they are extremely fragile and nudging/sliding will break them. They might say something like "you're cheating!" if they see you doing slap saves, nudges, and shimmies.

Ultimately it's very similar to auto racing. Each league and venue is different. A certain style of racing might work great on one track and not on the other. One sanctioning body might allow faster tires, the other might not. Rubbing is racing is fine in closed wheel stock cars, it's a disaster in open wheelers.

If an operator or organizer wants sliding, they'll make sure games can slide. If they don't, they'll make sure they are on rubber feet and the tilts are sensitive.

And it does look like the minority opinion is the "cheating" one... I mean shit, even the emoji is rocking that tilt bob!
