you are mixing up 2 things oxidation - corrosion , copper is very very slow when it comes to corrosion but oxidation takes place within much lesser time

just so you know copper oxidation produces "patina" (copper sulfate) , this patina is what protects copper from corrosion and this is a natural process . so yes the nickel is used to prevent oxidation cause it would make the heatsink base all ugly and might even alter its heat transfer properties (not 100% sure about altering the heat transfer properties)

All I can come up with is that nickel is cheaper than copper but then you have an extra step in the manufacturing process.
if you look carefully at thermalright heatsinks for example you ll notice that most of them have a copper base w/ nickel coating ...so i dont see how nickel being cheaper has anything to do with it ..if they were trying to save money they would just use nickel vs copper nickel coated.

Maybe oxidized copper doesn't dissipate/transfer heat as well as a nickel coating? So when the copper is all shiny, it does better, but it won't be long before its all dull.
