Isn't this just a change in orbital inclination?
"Just" is one of the most dangerous words in science and engineering.
Plane changes are very expensive in terms of delta V costs. Changing orbital inclination is a plane change. The cost to make an inclination change from a circular orbit to another circular orbit, with no change in orbital altitude, is $\Delta v = 2v\sin(\Delta i / 2)\ $.
For example, the delta V needed to change from a geosynchronous orbit with an inclination of 28 degrees to a geostationary orbit is 1.4 km/s. The delta V cost to successively go from a low Earth orbit inclined at 28 degrees to a geostationary orbit inclined at 28 degrees and then to a geosynchronous orbit is 5.3 km/s.
That three burn sequence (one in LEO to transfer to geosynchronous altitude, a second at geosynchronous altitude to circularize the orbit, and a third at the node to transfer to geostationary) is not how it's done. Delta V costs are nonlinear, thanks to the nonlinear way in which gravitation works. The result is a savings of about one km/s compared to that three burn sequence, but it's still more expensive than launching from the equator.
Regarding the wikipedia page on delta V budget, you have to take that page with a huge grain of salt.
