Did ISU lower the quad jump value after 2002 Olympics because of Goebel? I don't think so. ISU trimmed down the quad value after 2006-07 season because Brian Joubert won every single competition he entered that season and got his first World Championship title. It seemed that he had no competition and unstoppable at that time. This quad value cut down effort has created the infamous quadless champion era from 2008 Worlds to 2010 Olympics.
In a sense, Plushenko was robbed in 2010 Olympics. Before 2010 Olympics, no one has ever finished SP over 90 or even close to 90 without a quad. But it had happened first time ever in 2010 Olympics. So Lysacek was over scored in SP which had given him the overall win on the LP day.

Short Program Score Controversy
Plushenko's short program drew much praise from the International press which hailed him as the "King" of figure skating who had returned.[16][17]
It was the score for his short program that most Russian analysts say ultimately deprived him of the highest medal.
Going into the free skate, less than a point separated Plushenko, Lysacek and Daisuke Takahashi of Japan. Plushenko was the only one of the three to land a quad in combination with a triple toe loop. "I did a great short program but didn't get the marks I deserved. When I asked why, they told me I was skating early and they had to retain top marks for the last group," said Plushenko.[18]
The scant difference in the scores, a virtual tie, was slammed in the Russian media as dubious judging.
“They ‘buried’ Zhenya (diminutive for Evgeni) before anything could be done. He should have won the short program with a 4 to 5 point lead, in my opinion. A short program is a technical one. And a 4+3 combination changes everything here because it shows that you’re capable of doing more than others," said famous Russian coach Tatiana Tarasova.[19]
Plushenko thought bias was clearly demonstrated in the scoring and expressed dismay at the Russian sports officials: “After the short program, three judges placed me 21st and 22nd for skating skills. These people came to the conclusion that I cannot skate at all. Given the situation, it’s hard for me to understand where were our judges and the administration of our Skating Federation? Why couldn’t a protest be filed following the short program? This [kind of judging] should have been prevented at once, because I don’t believe my skating is of such a low level.[20]...I should have had at least a 5 point lead over my competitors. In the end however, the gap amounted to a mere 0.55 to which our Federation did not react at all.”[21]
The Russian Olympic Committee refused to provide legal support to Plushenko, who was going to protest the results on his own, citing the new ISU rules as barring such actions.
“Under the new ISU rules a complaint maybe lodged only if a calculation (mathematical) error occurs. If the judges err in interpreting an element or its level of difficulty, it is considered a “human error” which can not be challenged...No lawyer would take on representing Plushenko's interests as no provision for challenging the judging under these circumstances exists,” a source from the ROC was quoted as saying.[22]
Still, the head of Russia’s Skating Federation, Valentin Piseev, came under heavy criticism at home for not standing up vigorously enough for Plushenko in the face of ‘the judges’ arbitrary scoring.'[23]
“Evgeni’s silver medal is a colossal result. The result achieved by him, his coach, choreographer and his spouse. But if the Federation had stepped in, he would have taken home the gold,” said Irina Rodnina.[24]
ISU did lowered quad value after 2007 worlds, not during 06/07 season, particularly aiming Brian Joubert's win.
