Terry Moore happened to be the first major player to understand and select a main offensive shot taking advantage of the moment of the metal rods, utilizing more power and speed without loss of target control. The same way Hans Friedrich Kircher did when he couldn't shoot with his hand after his injury.
It's just another logical progression in the game, utilizing spin and physics. Pretty much the same progression as when the pull shot was first heavily utilized. Unless you believe that they were doing stroke pulls and pushes, instead of just kicks when foosball tables first appeared. The same probably applies to hockey, and to pitching in baseball. It never ruined the game, but instead enhanced it. It allows those who never figured out the proper nonrecoil pull and thereby damaged their musculature, nerves and tendons, to continue playing for years, without loss of accuracy or power. And their sons AND DAUGHTERS who won't have to go through neanderthal pain and hardship to get good at their parents' sport.
It only ruins those who never respected progress or new techniques and who still dream of going back to their fantasy world for a perpetual second chance. Same guys who keep thinking the championship NFL team of their childhoods 30 years ago should survive a 16game season today against modern teams and still win out. Most well-adjusted older players who still have the competitive fire enjoy the newness of learning another shot like the rollover, which has evolved into its own series. And enjoy learning how to block another deadly option, like learning to hit or pitch curve balls in the American League after years of fastball variants in the National League, or vice versa.
Even real field soccer now allows vulcanized or grip striping on strikers' shoes, which allows previously impossible curved and sliding strikes that were unthinkable a couple of decades back. Customized or standardized rubber snap-on booties or wraps for selected foosball figures may be the next technological thing coming. We could call them fbooties or ftoes.
