anodizing is a coating, over a material which is prone to corrosion

this is why there are ASTM testing procedures to 'quantify' corrosion susceptibility and rate
there is nothing that Dtek or any mfgr can do that will make aluminum as corrosion resistant as copper, particularly when 'mated' to a copper component
marketingspeak, not good - not accurate or correct

I didn't see anything in Danny's statement that led to believe that the coating is "perfect", nor "infinitely durable". As theetruscan stated, it's a question of quality, never mind the spec (who follows specs anyways?)
Sproket: copper is much harder to mill than Alu.
