The Erebus cars, driven by Lee Holdsworth, Tim Slade and Maro Engel in 2013 finished the championship in 20th, 22nd and 28th respectively while van Gisbergen finished fifth in his new Tekno Autosports team that used Triple Eight-supplied gear, winning two races and banking eight podiums.
The decision had little to do with gender or personality but was quite clearly about competitiveness. A lack of loyalty might have been a fairer criticism.
There is definitely an argument to say that van Gisbergen didn't paint himself in glory with how he handled the 2012-13 off-season but Klimenko's dummy spit at a time when the sport is applauding van Gisbergen reeks of sour grapes.
Klimenko has been a welcome addition to the Supercars scene bringing a big personality and colourful approach to her team's racing. She remains a popular figure in the paddock too but she's being very unfair in her criticism of van Gisbergen.
It is even more surprising given Klimenko's own driver David Reynolds scored the team their first podium finish of the year on Sunday.
